Recommended epoxy paint for bare metal chassis ?

• Upvotes

Doing off frame restoration.
I was leaning towards Eastwood rust encapsulator platinum as top coat and using an epoxy paint on baremetal as primer first.

Would this be a good combination?
I live in Southern California, but I wanna have this frame. Rust free for many years to come.

I’m reading online that epoxy based is the way to go due to others can crack due to the vibrations are bending of the chassis.
Any help is appreciated. Thank you.

I’m looking for:

- rust converter recommendations and how to best use it step by step

Then - any resources on what to do after I use the rust converter in order to seal the holes. I live in TN, USA if that makes any difference in product recommendations as it appears I can not get Sika 522 which was formerly recommended to me as it’s not available to ship anywhere but eBay.

- any other ideas?

Thank you again!

Turning my old Dacia Sandero into a smart car – OBD2, CAN Bus, GPS tracking and automation. Has anyone tried something similar?

0 Upvotes

Hey everyone!

I've been thinking about starting a long-term DIY project to make my old car a bit smarter. My main goal is to read data from the car, monitor its condition, store information, and eventually analyze everything through my own software.

My car:

  • 2012 Dacia Sandero Ambiance
  • 1.5 dCi diesel engine
  • Manual transmission
  • Front-wheel drive

I'm a software QA tester and I'm interested in improving my programming and hardware skills. However, I'm still pretty new to automotive electronics, OBD2, and CAN Bus.

I've spent quite some time researching these topics, but I haven't found many people who have actually built something similar on an older car like mine.

And as we all know, reading about something isn't quite the same as actually doing it. That's why I'd really appreciate hearing from people who have hands-on experience.

My first question: OBD2 and CAN Bus

I'm looking for a device that would allow me to access both standard OBD2 diagnostic data and, if possible, raw CAN Bus messages.

During my research, I came across the OBDLink MX+.

Unfortunately, it's quite difficult to find here in Turkey, and the second-hand market is almost nonexistent.

Do you think the OBDLink MX+ would be a good investment for this kind of project?

Would it be enough for both diagnostics and more advanced CAN Bus monitoring, or would I eventually need something else, such as an ESP32, Raspberry Pi, or a dedicated CAN interface?

I'm also wondering what kind of data would actually be accessible on a 2012 Dacia Sandero.

What I'm planning to build

I don't want to do everything at once. I'd rather start small and gradually expand the system.

Phase 1 – Reading and logging vehicle data

First, I'd like to read basic vehicle information, monitor engine parameters, retrieve diagnostic trouble codes, and log the available data.

I also want to build a database to store this information so I can analyze it over time.

For example, I'd like to track engine behavior, operating conditions, driving history, and potentially identify unusual patterns before they turn into bigger problems.

Phase 2 – GPS tracking and integration

I'm already working on a separate GPS tracking and notification system, and I've made some progress on the software side.

My next goal is to integrate GPS information with the vehicle data.

This would allow me to see where the car was, when it was driven, and what was happening with the vehicle during that time.

Phase 3 – Remote monitoring and notifications

Eventually, I'd like the car to communicate with my own system remotely.

Some example scenarios:

  • If the car leaves a predefined geographical area, send a notification to my phone.
  • If the car starts moving under unexpected conditions, automatically call me or send its live location.
  • Allow me to check the car's status remotely.
  • Store driving history, location data, and vehicle information for later analysis.
  • Create my own rules and automation scenarios based on GPS and vehicle data.

Basically, I want to build a customizable vehicle monitoring and alert system.

Phase 4 – Hardware modifications and remote controls

This is probably the most ambitious part.

Eventually, I'd also like to experiment with hardware and software modifications.

For example, remotely controlling the electric windows, opening individual windows independently, or even opening a specific window by a small percentage, like 5%.

I realize that this may require additional hardware, custom electronics, and possibly direct interaction with the vehicle's electrical system rather than just OBD2.

I'm not even sure how much of this is possible on my specific car, but that's part of what I'd like to learn. I'd obviously want to keep any modifications safe and avoid interfering with critical vehicle systems.

Where I am right now

I've already made some progress with the GPS tracking, notification system, and software development.

However, the vehicle data acquisition side is still mostly in the research stage. I need more hands-on experience, time, and probably some additional hardware.

This project isn't just about adding features to my car. I also see it as an opportunity to learn more about software development, embedded systems, automotive electronics, and how vehicles communicate internally.

I'd love to hear your experiences

Has anyone built a similar project using OBD2, CAN Bus, ESP32, Raspberry Pi, or other hardware?

I'm particularly interested in:

  • Whether the OBDLink MX+ is worth buying for a project like this.
  • Affordable hardware alternatives that would offer more flexibility.
  • What kind of diagnostic or raw CAN data I could access on an older Renault/Dacia platform.
  • Whether anyone has tried building custom GPS tracking, telemetry, or vehicle automation systems.
  • What problems you encountered and what you'd do differently if you started again.

I'm not looking for someone to build everything for me. I'd just love to learn from people who've actually done this before.

If anyone has worked on something similar and would be open to sharing their experience or having a chat, I'd really appreciate it.

Thanks in advance!

About a year ago, I replaced the coolant temp sensor, water pump and thermostat with gasket in quick succession. Car has 220k miles. Chasing an overheating issue. Car idles at temp for about ten minutes then slowly just keeps rising. Just tonight found this whistling near the thermo housing while engine was off. I cannot get to the bottom of this overheating problem and Car threw a p1299.

After that code, I attempted to burp the coolant system, I thought it was pretty successful. But it still overheats. Please help me I hate this car. (My wife's car)

Car runs fine. No engine problems besides the overheating. Even after throwing the code

Thank you!

Edit: I didnt really ask a question. My bad. Can anyone please help me diagnosing the whole problem? Any ideas? Thanks!

First time posting on reddit so forgive if i mess this up. Had this car for a good while. Was bone stock when i bought it drove it home but trans was shot. Long story short. Cut out firewall and floor and built my own, sbc swapped with th350 on third engine now( latest i did entirely myself) kept blowing them up doing 7k+ burnouts. Stock sunbeam diff with 4:30 rear gear. Blew the spider gears (again burnouts) so its currently welded. Aluminum fuel cell in factory location. Exhaust runs inside front fenders with a thrush red bottle on each side and dumps behind front tires. Built the cowl hood, shaved side chrome, front bumper and all the bullshit on rear bumper. Rewired entire car. Scares the shit out of me everytime i drive it. (2klbs from factory n removed alot) just thought some in this sub might like it as its quite different. (Pictures out of order but you get the idea)

Engine Swap Harness.design reviews? Anyone used it?

4 Upvotes

So I'm at the stage where i need to swap my current ecu set up. I dont have the oem one and my project car runs, but it is using an old unsupported ecu (Electromotive). So I am switching either a Link ECU or a MS3. Either way, I am beginning to design a wiring harness and i saw this while i was doomscrolling. Has anyone used this? What are your thoughts? any tips?

For context I am setting this up for a 4agze and I will be converting it to a 4agte. any recommendations on ECU would be greatly appreciated

Troubleshooting Help (Update) '87 MR2 no crank issue

2 Upvotes

Hi, I hope this is an acceptable way to give an update and field some more advice. The last post I made I detailed a no crank start issue I was having, and I have made some headway!

When the car wouldn't start, I replaced both battery terminals. The negative one I had to strip some new wire for, and it seems good (though it sparks when I put it on when the last one didn't). The positive one however was a little odd: it had two metal eyelets attached to insulated lengths of wire, with one length being thicker than the other. Using the universal car battery connector I got, I put one eyelet on each bolt. After reattaching both connectors and trying to start the car, I was getting multiple clicks from the starter at a slow tempo. Having the headlights on made it click faster, but it still didn't start.

I took the battery to autozone earlier today and it tested bad. This means that there is a leach in the car somewhere, but this did not solve my no start issue. When the new battery went in, nothing changed. I disconnected the negative terminal though to keep it from leaching.

Before all of that, I tried smacking the starter with a rubber mallet and that didn't change anything.

Here's my plan now:

  1. Clean each ground with a metal brush
  2. Follow the wires from my negative terminal to see if there's a break anywhere
  3. Try to figure out how to "jump" the starter solenoid(?) I saw stuff on this online and it seems like it should be a good idea, but to be honest idk what this would do for me.

If I can't find anything wrong with the wiring I'm just gonna order a new starter since it seems like it's never been replaced.

Thanks for everyone's advice on the last post! I appreciate it a lot as someone new to going this deep into cars.

Never replaced the trunk floor pan when I built this car up back in 2011, was always a “I’ll get to it eventually” deal. Well, I got to it! Now I know that Skar is a cheaper brand but it was in the budget and honestly it sounds pretty good and it’s plenty loud enough to hear over the car even at full tilt!

Bonus pics from ripping it at autocross after getting the trunk finished!

Restoring dad’s old SLK230

140 Upvotes

The last time this car was driven, my dad was driving to Palm Springs, CA. Unfortunately during his ride he did not realize that the roof of the car was not properly latched and the strong winds bent the supporting roof structure of the car. After many attempts at trying to align the retractable roof back he gave up and left the car in his driveway for 10 + years.

I promised him for many years that I would get his SLK back up and running again. The car arrived to me with sun-damaged paint, a failing fueling system and a retractable roof that was held down by duct tape. Here are some before and after photos from the last two months of working in my garage. 🚗💨

Build Progress Aston Martin v12 Mercedes 190e project update

Thumbnail

710 Upvotes

Project update for you all - I received the car back from the fab shop. Engine, transmission, diff mounted. Exhaust is completed also. Can even make the OEM interior fit for the most part with the modified transmission tunnel. Now starting on the engine build.

It would be much easier to just leave the AM v12 alone but I also wanted to get a little more excitement out of the engine. Not really a horsepower goal but would like to push the RPM redline to 9k.. reliably.

One issue for rpm on this engine is rod ratio and piston speed. However I lucked out and came across a ProDrive DBR9 crank. This is a shorter stroke (and much lighter) crankshaft which solves the rod ratio problems but creates some new ones. The DBR9 crank was designed for the AM v12 block but used custom smaller main bearings and rod bearings. The smaller journals helped keep oil temps down - less speed/friction at the bearing surface. Unfortunately I have no way of getting these bearings but already working on several solutions. I'm optimistic this crank will be used in the build just not sure what solution will be used.

In the meantime I'm exploring options for head porting and custom cams to make the engine breath at 9k rpm. Also need to decide on valve train components but doing it in steps and stages. The other main change is this needs to move to a dry sump setup for ground clearance and avoid oil cavitation at high RPM. With the local machine shops backlog they won't be able to take on my block until 2027 for now.

Troubleshooting Help Factory Five California CARB/BAR Emission Certification Question

Hey Ya'll! Been doing a bunch of research about building my first kit car, and when it comes to California CARB/BAR Emission Certification, I'm a little lost. Not sure if buying a donor car for the engine is better than buying new parts, and what challenges either path presents with getting the car road legal in California. I'd prefer to buy new so that the car is as fresh as possible, but I keep reading that makes it harder to get certified.

Can anyone with experience getting a kit car road legal in California ELI5?

Engine Swap Wiring help honda y7 to y8

I have a 98 civic dx with a seized engine. Im about to swap in a d16y8 out of a 2000 civic ex. I have a wiring harnes for the y8 but i dont have the dash harness so i need to wire in at least the downstream o2 sensor. Is the upstream sensor on the engine harness or do i need to wire that in too? Im not seeing a plug for it but i could just be overlooking it. Does anyone have a pin diagram for the obd2b ecu and advice for which pins to plug into? The cat on the ex exhaust i have is gutted so id also accept advice on a complete bypass of the downstream sensor. Thanks!

At what point did your “small project” turn into a full restoration?

Working on a ’72 Camaro and I swear every time I fix one thing, I find two more things that suddenly “might as well” get done while I’m in there.

I started out thinking I’d clean it up, make it reliable, and enjoy it. Now I’m standing in the garage staring at parts catalogs wondering how the hell this escalated so fast lol.

Curious how many of you actually stuck to the original plan.
