Folks, how do you approach fixing small chips, dings, and scratches on your airgun finish without repainting it? Like the ones I've posted below. It looks like enamel was chipped off. I know you can simply use Birchwood Casey touch-up pen, but it would not fill gaps and in general I did not have good experience Birchwood touch-up pens before except if it was used on anodized finish. I was thinking of trying to use something like Testors semi-gloss enamel paint. Fill the gap, let it dry, polish excess paint off with fine grit sandpaper, and repeat until I level up the chip edges and make it disappear. Or maybe some other type of touch-up paint would work better. Or maybe it's a bad idea altogether . Before I try anything, I wanted to ask for the wisdom of the community here and see if anyone has a better idea or experience with repairing such small imperfections on a gun finish. Hope to hear from experts soon. Thank you guys!!!
