my father in law wants to semi restore on old 22 that his father gave to him. he wants to give it to my brother in law as a gift. Now onto the question. the barrel finish is fucked, and i mean fucked. can he give it a light sanding with a light sand paper, maybe some wet sanding, and then re-blue it? are there any good products out there for this? or should he just send it somewhere and have it done? cliffs: father-in-law wants to restore heirloom rifle. barrel needs refinish, any cheap good solutions?
