Used mineral spirits to clean the grease off, but just used a paintbrush; will dig out the brass brush and give that a try.
Yeah, the paint is especially thick on the magazine, and a really gloppy job it was, too.
If the spirits and brush don't work, will have to see about either some paint stripper or possibly having it blasted.
Any recommendations as to paint for new finish? I've read of Aluma-Hyde, any other good ones you'd suggest? And thanks for the information, guys.
