I had a chance to take out some of my old favorites. My Mav 20ga, AR, and .22 WMR Ruger. What they all have in common are spray bomb camo jobs. I used a range of "techniques"--normally making a contrasting stripe pattern with some cargo netting, mixed with a little sponge painting. It gives them a kind of "flecktarn" appearance that actually works pretty well.
It's amazing what you can do with a little Krylon, cargo net, and sponges.
Have any cool paintjobs that you were proud of?
