Anyone painted a plastic stock?

Rough the stock up a little, use a good adhesion promoter followed by a paint designed for plastic like Krylon. When your done the surface will still be susceptible to surface sratches and rubs but is easily touched up.
 
Prep the surface with an electrical component cleaner to get rid of oil from the rifle and your fingers. Spray color and when dry spray several coats of automotive semi gloss clear coat. This gives a relatively durable finish.

I also do this with stainless gun barrels, flat black then semi gloss clear coat.

This is my method as well but I clean the surface with alcohol instead of electrical contact cleaner. Just depends what's on the shelf.
 
Prep with alcohol and spray with Krylon, then do a top coat. I like doing a base coat of the light tan, then laying some wheat on the stock and do some shots of darker brown. You get a cool wheat field camo effect.

I've done a few, they end up looking good. Not nearly as durable as the bake on professional quality paints, but you can touch them up with another shot of Krylon. Good for beater hunting guns.
 
As with all painting, it doesn't much matter what kind of paint you use if you don't do a good job of surface preparation.

I've used Krylon on several plastic stocks (H&R and N.E.F. Handi-Rifles, a Traditions muzzleloader, a Marlin 795, a Savage 24F) and with the same care in preparation and application had no significant difference in the results. It does get scratched or worn as hunter5425 said in post #2, and is easy enough to retouch. I used a satin clear coat on one of them and it is a bit more resistant to wear but it's shinier than I like so the rest didn't get that treatment.
(I don't do camouflage patterns, I just don't like black plastic much, partly because of heat on a sunny day.)

In addition to alcohol/degreaser and roughing up the surface with some sandpaper, I would suggest your first coat is a thin layer of automotive rocker guard spray. It adheres like glue, holds paint well, and has some give to it so that your stock won't chip/flake/scratch as easily. If you spray it, then it makes sort of an orange peel texture on your stock. It will make your flat/matte paints a little less flat/matte but still far from being shiny. On a stock that I painted I also taped off grip panels in the shape of checkering and sprayed that with clear traction spray like you would use on stairs for grip. It's got a bit of silica in it and is epoxy based by Rustoleum. It'll give you a no slip grip.
 
I use some sand paper to rough up the surfaces then clean with brake cleaner. Then I do the painting with krylon camo and finish with some krylon clear flat for 2-3 layers.

For my ARs I just clean with alcohol then go to town with krylon camo and call it a day.
 
I did the factory T3 stock. Same as above, light scuff with some fine sandpaper, clean with alcohol to remove any oils or dirt. Then I applied grey and white paint with a sponge to give it a winter "manners" style camo pattern.
