I apologize for asking this post again, no doubt this comes up a lot but I cant seem to find the past posts on this. I remember some kind of spray enamel paint is safe and wont eat up the pink xps foam. Does anyone know the exact brand?

There are a couple, that used to be around. Not sure if they're still there in even semi-affordable prices. I know that hobby lobby has some in the mini spray cans, but they are definitely not cheap.
You can sometimes find some at hardware stores if you ask at the paint counter and they have someone who knows what he's doing since some of the spray foam and similar also melts with the stuff...
The main issue with finding it is that the solvents in the cans that don't eat foam are more regulated than what's in the normal cans...

Krylon H2O is designed for plastic. Have not tried it myself.

It would probably be cheaper in the long run to buy an airbrush and some paint.

I know I'll sound like a broke record here, but I regularly use Krylon spray paints on foam, as long as you don't spray from too close, you can do it without the foam getting eaten, about 6 inches away, but it takes more of the paint to cover the foam and if it's windy, I most always spray out doors, the wind tends to blow the paint away because you're far away from the foam.
If you're uncertain, take a scrap piece and spray the paint from different differences to see how the foam reacts.

There are a couple of florist sprays that are safe for foam. I just brush on a thin layer of black (color of your choice). Once the thing has a coat of paint you can use any spray on stuff or glue you choose.

I found that if I get the the amount of color as well as the distance between foam and spraycan right, I can control (at least a bit) how much foam gets eaten, which adds a nice rocky texture. However if I simply want to paint the foam up, I almost always do it with acrylics and a brush because the cheap spraypaint I used so far does a bad job covering the foam. Brushed-on acrylic color is way better, and also not very much slower, than spraying.

Thanks all! I ended up just brushing on acrylic mixed with water. It was a pain but o well. Working on some more rock texture pieces, and I really scored them up hard with a knife to make them look like craggy rock. It made for an insane amount of little holes and lines to have to work the paint into. Thanks again.
