WOW Shaman that looks good. It looks like you base coated them added color. Is there any prep wok, ie: sanding stripping, priming? Was the gun blued or matte, thinkin about doing an 11-87 premier, it got real scratched up using a saddle scope mount.
No serious prep work. I had to remove all the old tape-- that tape left a REALLY gnarly residue. The original finish was blued. The hard part is masking off everything you don't want painted.
As far as priming, the Krylon Fusion is its own primer. All I did was A) spray everything one color (tan) and then go back and spray everything another color (black) to make sure I'd covered everything.
