Ugly paintwork.

Honestly , I think I could live with that ! Guns ( most) to me are like my pickups ,suv's & cars, I run them till they scare me for reliability or not worth putting a lot
more $$ in, then what I get for trade in is just worth getting rid of it as it has done the service I got them for . I know I may think differently than most, but they are to use , enjoy & get all I can out of them ! I've known many that don't want to put miles on their truck or take a nice shotgun in the briars ( bought it to hunt rabbits/grouse ??) . I don't want to see my truck set in the driveway, I want to get to work, shooting spot ,etc & if I was hunting ,I never found much game in the open ground. Could just be me ... Anyway good luck with your project!!
You're not alone, I don't sell my pcps, i put a lot of thought when buying one so I don't buy an undesirable.
 
If I am after something that could possibly be spooked by my rifle I might wrap the visible parts with that removable camo tape. Painting a stock, I can see that, painting the metal work, no freaking way.
Painting metal only becomes a problem for the ones who don't understand the steps needed to do so. You can always change it back factory.
