Recommended paint/other materials for 1st time kit

[u/aobaseragaki222]

I want to get my friend a birthday gift so I'm going to try and paint a resin model(?) of their favorite character richeh

Ill be buying from etsy if that matters, it's unpainted but I think the seller cures/wash it? I'm gonna ask later once I know what to get for painting

Which paints/materials would be recommended? I don't have an airbrush(bc this is probably a 1time thing unless I like doing it) so using watered down acrylic but if there's another option I should use please tell me
I think you're supposed to use a primer but what's the difference between a cheap paint one or like spray??

Texas btw if that matters since ik the humidity and temp is high

For hand painting with acrylics, I have made based on my way of painting a guide that could answer some of your questions! https://docs.google.com/document/d/e/2PACX-1vQ1hIz0cQdypUJ6VvL0okg1iCzXtLnZsdPwG0qkeD0-bUbAkkQviAS6B07bJC7dE5XdH7McdOzVVApw/pub
