Actually, it's really straight forward, you want to tone it down right at the start, by using a black base & spray that. then mix your gold flake with clear with a few drops of black in it, this will dull the usual flash of the flake right away. - spray this. Next, you want to pick the kandie paints to do your cammo, usually this would be a brown & green, or something along those lines ( I would use HOK Kandy Rootbeer, and a kandy green ) ..... so now you want to tone these down, again, by using black, so put a few drops of black into the colors, a bit at a time & test as you go to see if the tone is what you need. do your cammo pattern & clear - As far as the dull goes, your on your own with that, cause this makes no sense to me, it will just kill the whole look of the flake.-it defeats the purpose of the flake, which works by using light; when you remove the gloss, you remove effect. Trust me - the cammo flake idea is weird enough,without screwing around with dullcoat. If you need to get flake, try a place like Paintwithpearl.com - Good luck
