Yes, prepping and sealing up air compressor tanks is an extremely popular application for the KBS Tank Sealer System. Most air compressor tanks develop rust over time from the condensation that develops on the inside of the air compressor tank and this rust can eventually cause leaks in the tank. For this reason, many people prep and seal the inside of their compressor tanks, so they do not have to be concerned about rust forming in the tank down the road.
For air compressor tanks that already have a pinhole leak (tip of a pin), the KBS Tank Sealer System will seal up that pinhole leak and protect it from getting any larger.
