Polishing the barrel and hood
Get you some mother's mag and aluminum polish, couple of terry cloths, one to apply polish and the other to shine. Get out a movie and watch it while polishing away. You will have a brite shiny barrel and hood in no time, and since the barrel is Stainless, it will not rust nor will it pit or get ugly so long as you keep it slightly lubed as you should anyway. Works great..I do all my guns. Oh and by the way, use the same polish and cloths on the feed ramp and polish it to a mirror shine as well. Improves feeding problems.
