Lessons learned but advice needed

I had decided to redo the finish my savage model 64F and to also add a few decals to my ar. Well I decided to paint the stock with fusion krylon as a base coat and go over that with a red and black swirl pattern by thinning out rustoleum and using a small model car decal spray gun. Dont do it, you will NEVER get the paint thin enough. I decided to fill in the sig logo engraving on my ar-15 with green, it looked good but I decided I wanted to remove it and leave my ar-15 stock. Sprayed it with citristip and scrubbed with a tooth brush, now its left a white calcium finish in the fine lettering and I cant seem to get it out.

How would you remove the residue from the lettering? Anyone have a prefered brand of rebluing kit (I've did a few shotguns but I havent found a kit I prefer) Tomarrow I'm going to try break cleaner and a rag to scrub the lettering.

not much help here, but a little lesson on paint. Some of the higher grade paints have "etching primer" in them. Think of it kinda like acid that dissolves a little bit of material, fusing the paint and the material as one. That may be what has happened.

I can get a wet cloth and scrub and it "disappears" but as soon as the water dries its back. Going to use some break cleaning fluid later. The paint that I used was model car acrylic paint

I'd be willing to bet you stripped the finish. I have seen that when using brake cleaner to clean a mg before.

I'd be willing to bet you stripped the finish.

Indeed. The white deposits that the OP is seeing might be aluminum oxide from the corroding receiver.

stripping the anodizing off? Seriously thats possible with something as tame as acrylic paint? Anyway to repair it? I was also told that brake cleaner would not harm the anodizing. Will non chlorinated brake cleaner really hurt the anodizing? That was going to be my next attempt after just soaking it with more citristrip (I left it on for about 15mins the first time and it didnt damage the paint that had gotten on a gap in the tape)

I've already tried acetone and paint thinner and hot soapy water with a stiff brush

That photo doesn't help too much. Can you try getting the roll mark in focus instead of the table? I kind of looks like the anodizing has been stripped/worn out of the roll mark, as others have suggested, but I don't know how you would have done it. If it were mine, I'd just leave well enough alone (and never have filled in the roll mark in the first place). You could also just try filling the roll mark with a matching black paint.

Try some thin oil like Rem Oil and let it soak for a bit. It may take a few applications. Brake cleaner will only make the residue worse. Type III anodizing is pretty tough. If the stripper had removed the anodizing, the receiver would now be bare aluminum

I tried more acetone today, nada it seemed like it evaporated too fast. Same thing with brake cleaner. Soaked it with more citristrip and got an rough lint free cloth. Soaked with citristrip for about 45mins and scrubbed. Alot of it came off, its just gonna take a crap ton of scrubbing. Will never paint the rollmarks again. :banghead:
