I cannot say that's simple; however, I have to do that – not because of the landing gear failure and crash, but f...ing Seagull tank stopper came out.
I noticed that there is no any fuel proof inside the tank compartment. Actually I did some Lastrikote spray, but couldn’t reach all the structures. Vietnamese plywood is the best to absorb oil from the fuel. It almost totally destroyed the bottom section of the fuselage. Tried everything – kitty litter, corn starch, K2r, heat and absorb -no way. It was seating there like for good. The frame needed some balsa and plywood to be changed.
