To all,
Here’s how I did mine. To get to the correct tint of green, I went to Home Depot and bought a quart can of Hunter Green Rustoleum enamel and a can of their Rusty Metal Primer. They are thicker than anything in a spray can.
I mixed 1/2 can of the primer in with 1/2 can of Hunter Green. This proportion gave me a very drab olive green/brown. By mixing 1/2 can of the primer with a full can of the green, I got a very nice dark olive green. You can mix to match your desired shade.
Because Rustoleum is owned by Valspar, I went to the automotive finish supplier and bought some Valspar catalyst to add to the base dark olive green. The catalyst hardens the surface and cures it in short order. The finish is much more resilient than anything in a spray can.
I also used the same process to paint my Brownells Brown colored AR proto stock, grip and front handguard but used only the rusty metal primer. It turned out to be a nice eggshell/semi gloss finish. I also bought a spray can of plastic adhesion promoter and sprayed the plastic parts (after using a grey scotchbrite pad to scuff it up) just prior to applying the finish with my Iwata spray gun.
Lastly, I use 3M 36058 rubbing compound to get the level of sheen I was after. It doesn’t contain abrasives but works great unlike ordinary rubbing compound. Little work to take down the finish.
The final finish sticks better, is more durable, cures damned fast and because Valspar owns Rustoleum, there is no compatibility issues whatsoever. I will never go back to spray cans alone again.
