RE: To avoid disaster... check your fuel tank seal regularly!
Roger, I just found this thread. You referred to KR-2 (maybe K2R), where do you find it? I used to find it here at the Publix Supermarkets but they stopped carring it. I have looked all over town without luck. That is one of the best products I have used. It will suck fuel and oil from very badly soaked balsa wood.
