Wait a minute, your looking way to deep into this RobRed. These are NOT investment grade guns we're talking about here. If they were, there would be no reason to paint the cheap plastic stocks as the rifles would have come with HIGH GRADE walnut or fiberglass stocks. Yes I prep the stocks with acetone, and paint them. No issues with paint not sticking, they've lasted for years of use. NO NEED for HIGHlY expensive automotive paints and equipment. As well, I do not use solvents as these are blackpowder guns that I clean up with Windex or rubbing alcohol. Never had any issues with any of my painted stocks using the paints I have listed above. The prep time is nothing. All stock components come right off the base stock, making it very simple. Disassemble the gun, then the stock, prep and paint. Let cure a week, reassemble and enjoy for years to come.
