Decided to send my QuickBuild Tanks to a company named, "Weep No More" in MN. QB tanks have a bad reputation for leaking or eventually weeping. I don't want to deal with that, and especially after an eventual high-end paint job. Paul at Weep No More is recognized as a grea solution for Mooney and Van's aircraft guys. He chemically strips the ProSeal fro the tanks, removes the back baffle, and reseals it all in a three part process. Seven year warranty. Had to build a custom crate, which took a bit of time, but the tanks got there and back in fine shape. Paul also installed the trap doors, pickup tubes, and floats per my request.
