Hi guys, this is gonna sound like a silly question, but I'm anal with these things, so I would like to find a solution to preserve the BB white stickers you have on the bottom plates, while changing covers. I just bought a set of beautiful gold plated vintage shape covers (the same sourced by the Historic Makeover), and I'd like to make a clean job, preserving the original BBs base plates. Usually, when you put the tip of the soldering iron on the old solders, the excessive heat will burn the stickers, making them black...which I find extremely annoying (sorry). Do you guys have some tip to avoid that? Just to be clear, I'm talking about these white stickers; Thanks in advance.
