LMAO that’s funny. I am wanting to do the same with a Spikes Tactical lower that I have. I saw a YouTube video of a guy using acetone or fingernail polish remover and a brush. He said that the acetone will peel up the color fill without impacting the anodizing. I have not taken the time to do this, you may want to verify before you try but it looks very easy and painless to do.
