I've have my 29g with the back painted in black for over 2 years. I'M BORED !! I'd like to paint it a nice blue. I could use a razor blade to remove most of it. My worry is the unions of the glass that have silicone exposed. I obviously can't use a blade there, would have a heart attack if it began to leak. Can I use chemicals for those areas? Acetone, Mineral spirits, ect? Might the chemicals seap in through the silicone, or maybe the fumes be harmefull... Obviously I would make sure the room is well ventilated before using chemicals. Any advice?
