Hello, I have a very small rust bubble on the slide top of my blued government. Since it's in the sandblasted area I'm not sure how to get it off without making it look worse than it is now. Can somebody please advise me on this one? Thanks in advance
Take some Break-Free and apply liberally to the affected area. Allow it to soak in to the rust for a couple of hours. Then using a nylon brush scrub the area until all rust is removed. You then have to cover that spot or the rust will come back. I have used Birchwood Casey's touch up pen on a shotgun before and it worked fine.
