.."Krylon - Plus: very easy to apply (way easier than you may think), conceals just as well if not better than Duracote, can easily and quickly change colors/patterns. Minus: wears off (but is super easy to touch up)."...
Durability is increased 100% with the use of matte clear over the color. I tested that on an expensive aluminum screen door, shot it a different color with matte clear on top. It stood up to four teenagers for three years with no loss of color on the high points.
On the other hand, krylon with wear patterns breaks up the outline even more.
I plan on spraying my 6.8 build, the hard part is Krylon doesn't make Foliage Green. Yet. The rest of the furniture already is. Lucky me, I work at an auto parts house with a paint department. A half pint of matched color is an everyday thing. Using small smooth foam roller on very dry, I might be able to preserve the rollmarking in black.
POF is now offering FG anodizing on their piston gun. Maybe Rem/bushmaster will get the hint, some of us don't want licensed treeflage. Home dipping film kits are rumored on the market now.
