Painting Resin, The Proper Way?

[avpfan36]

This isn't predator related, but I really need some help with this. I bought a resin mask off of ebay, and want to strip, sand, and re-paint it. It's painted acrylic, onto BARE resin so right now the paint comes off very easily with just your nail or anything rubbing against it (like my jacket zipper). What I want to do is, strip off the existing paint but don't know what to use in order to get it off without having to scrape every square inch of it. From there I'm going to sand it down nice and smooth, cause the cast is quite rough. When it comes to painting it, would a primer be worth putting on there even though it's sanded? Lastly, what would I use as a sealant/clear coat on the paint? I want a matte or semi matte finish, and I don't have an airbrush to apply it.

Thanks

Youre going to have to hit it with a mousesander using some really high grit sandpaper and get it down to the bare resin, then Prime it with some automotive primer. To seal it, I'm not sure. Don't seal my paint.

yep, the way you are already doing is the way to do it. that's why i havent fixed some of my first paintups where i didnt prime first. it just takes a long time to get it back to raw resin. put on a movie or two, get yourself a beverage of choice and get to sanding.

So I ended up removing the original paint with a wire brush attachment on my Dremmel. Also tried sanding it down by hand, but the damn cast was too rough to get it nice and smooth like how I wanted it, so I didn't put much time into it. Re-painted it with both enamel and acrylic paint, and used a gloss indoor/outdoor varnish. Put two coats on so far, might do another 2...cause I don't want the paint coming off like like it was with the original paint-up. Acrylic paint on a bare, non-sanded or primed resin. By the way, I didn't prime it prior to painting, I figured the sanded surface was good enough.

Most primers are chemically different from regular paint. They're formulated to "adhere", or bond to a sanded, clean surface, which in turn gives the paint something to bond to. It's been my experience that paint really only likes to bond to other paint. The amount of coats applied doesn't matter if the first coat has nothing to bond to. Be careful with the mask and you should be okay. Also remember than acrylic paint tends to "dry out" and become somewhat "brittle" over time. I always use primer, no matter what I'm painting.
