Hi folks...feeling somewhat dejected...
MY QB wings arrived last August. I pressure tested the fuel tanks, and seemed ok. I filled them with avgas and UV fluorescent marker and no halos formed ae=round the rivets,or my flop tube installation. I pressurised the tanks and checked them under water ( senior management objected to me taking the tank into the hot tub!)
I then degreased the wings, painted with 2 pack acid etch primer then 2 pack epoxy, and put them away.
I came to move them to the hangar today as I need more space at home to hang the engine, and found 9 paint bubbles along the port lower rear tank baffle/wall seal!
I can't think of anything it might be other than a poorly sealed tank... unless anyone else has a better suggestion?
I've stripped the paint off and I'm pressure testing again... but the prospect of stripping the tank off and opening up to repair something that should have been done professionally in the first place is very depressing...
