I have a .308 Ruger American that is very plain. I want to have an artist friend of mine paint a nightmare before Christmas scene on the stock. She will use durable outdoor paint and will then clear coat it. My husband has a few concerns that I can't answer. He feels it will lower the value of the gun. I feel it would increase the value. The cost to have her do it is anywhere from $100-$250 depending on how detailed I want it. His other concern is the clear coat will make it unusable. Does anyone have any thoughts?
