First and foremost I am not asking about filling in my serial number for some tinfoil hat dumbass reason. I'm just talking about covering up the import stamps. I do not want to "highlight" them as some people do with trademarks. I want to fill it and then paint over it so it as if it was never there. Similar to mudding a screw hole in drywall. Bondo seems like an obvious choice but I'm guessing the shock of the weapon firing would crack/flake it off in a hurry. JB weld and sanding? Anyone have any advice for this?
