So I have the bubbles and flakes and corrosion that I’m sure most of you have experienced but it’s pretty severe on the snare side. Aside from neutralizing the oxidation, should I just pick the flakes and bubbles away? Sand it with fine grits? I assume if the corrosion under them goes unaddressed it will only get worse. This is a player/keeper so I’m not concerned with a total restoration. Any suggestions much appreciated!
