I accidentally got some acetone on a factory painted Stocky’s stock one time and it removed the paint in that spot. After looking into it, it seemed like the wiping with acetone would not likely harm the actual stock. I ended up rubbing the rest of the paint off using acetone without incident. Would I recommend soaking the stock in acetone? No. Just sharing that wiping the paint off in that case was easy and worked well. You could also call the stock maker and see what they say. I’d be more worried about getting into trouble sanding.
