Alright, I posted a few weeks ago about getting a shotgun from my dad. I bought some stuff to remove rust from blued finishes, and it got some off, but it won't get all of it off. Anyway to get something that will get some old, deep rust off of a blued barrel/reciever without ruining the finish?
Also, where are some good places to get some accessories for it (synthetic stock, magazine extension etc)??
Any help is appreciated.
