I've sealed and closed one of my leading edge fuel tanks, but I have a couple of pinholes I'm tired of chasing down, so I bought some slosh type sealant. The instructions state to make sure there is no water in the tank, but there are a few drops, I used water to check the back side sealing before I bought a pressure gauge. What's the best way to dry the inside of the tank? I have an air compressor, but it's been humid and raining lately, so that air coming out of it is probably fairly moist. Any suggestions?
