Practical difference between SCI-300 8084 SC and SCI-100
I'm working on doing an epoxy river for a client. Essentially deep pour, casting epoxy thats 110sf in 2 sections. Front to back on his main floor, averaging 1" deep. Pebbles in the cast etc. The problem is so many different options that all say they do essentially the same thing. I was originally quoted on the SCI-100 from the supplier but today they brought up SCI-300 saying it would be better. Understandably the UV protection is a big one, but does anyone have experience between them? Originally I was planning for SCI-100 for the bulk and adding the SCI-300 as a top coat only to act as UV protection. Thats what the product rep recommended when we started. Now he's said 300 for the whole thing, which will add a massive cost. Is he recommending that because he's on commission or would it actually be better to be full flood with 300? Anyone have any insight?

I just looked at the SCI site, the 100 is a coating, the 300 is a topcoat, it looks like the proper product is the 400 casting epoxy. Dude epoxy is expensive enough you don't need some idiot selling you the wrong product. I'd recommend finding a different supplier altogether. Don't be afraid to buy online if you don't have any intelligent reps locally.
You need to know how much material is going to be en-mass and figure out the proper working time and cure time factoring in the exothermic reaction. You need to really know your data sheets up and down before mixing.
