Krylon is as good. It will all wear, put a good matte clear coat over it. When I re-did my Stevens Tupperware, I found a Vinyl rain poncho in Woodlands real tree camo for $5.00 and wall papered it on the stock with 3M spray adhesive. It turned out great, so I did my Shotgun and AR furniture. If you can wall paper, you can do it.
I think I'll leave it Black for a while, then Maybe Marpat Marine digital.
