Here's my remington 770 (I know, I know not a great weapon to some, but sure is a tack driver and not one of the 16 deer I shot with it complained) in my first try at a tiger stripe. Lines are hand painted. Barrel and bolt done in O.D. Green cerakote.
Also here is my Mossberg before and after with Duracoat. I know it ain't Krylon, but its paint just the same. The Mossberg was bought used and in rough shape with a great bore. Also, the purple color is more brown in real life, just can't capture it with camera.
