I rattle canned a T3 stock years ago., Krylon paint. Did the base coat, put some leaves on it, painted more, different leaves and painted more.....functional camo. Then a clear coat.

Have had a couple flakes here and there, but just a blast of paint continues the camo pattern. Then again, it is a varmint hunting rifle that gets beat up a little, so I am less worried about a show room finish.
