Russell Croman Posted July 12, 2012 Report Share Posted July 12, 2012 My CTSW sits with one wing a couple of inches lower than the other, perhaps due to a hard landing at some point in its history. Doesn't bother me, except that if I fill the tanks all the way, fuel eventually transfers from the high wing to the low wing, with some expansion when the temperature rises, it then leaks out the vent on the low side. I've started topping off only just before a flight for this reason. From previous overflows, I now have some faint but noticeable blue (from the dye in 100LL) and brown (from evaporated mogas) streaks on the underside of the low wing where fuel flowed. Does anyone know of any cleaning product that will remove these stains without harming the finish? I've tried just using fresh fuel on the theory that like dissolves like, but the stains won't go.
