Because of all the “BS get over it” posts I have not read everything. Question, how did you scratch it? The reason I ask is that the blemishes look more like aluminum “painting” rather than true scratches. I dragged a barrel across the aluminum edge of a gun case and put a two inch “scratch” on it that looked very similar in color. The aluminum marked the phosphate finish, painting it, not really scratching the barrel. CLP and a ton of rubbing with a cloth finally removed it. In retrospect, I wonder if I had applied a little Aluma-Black to it if it would have darkened/removed it a lot easier. If you put a piece of raw aluminum in Aluma-Black, it will bubble and smoke, as it oxidizes, or whatever it does, the aluminum. I wonder if a little AB on a Q-tip applied to those marks might remove them in nothing flat. AB will not hurt a phosphare finished barrel unless you leave it on a long time, and maybe not even then. Worth a try?
