What recommendations for (or to stay away from) spray-on in a Flat Dark Earth color for an AR pistol? I'd rather not have to "bake on" anything but it's not completely out of the picture. The will most likely not see any hard use or throwing the gun down, etc. It's a new build with no more than 24 rds. through it. Any suggestions for what to use and/or what to stay away from? Thanks for any help.
