BTW, I forgot this. The LHS bought a Sig Rascal ARF from a guy that started to put the wing together, and epoxied the aluminum wing joiner into one half-upside down! I told him I'd fix it for him. They say they are covered with "Oracover". He checked and told me that it is actually Ultrakote. Anyway, I used Ultrakote when I made the fix and it matched and worked perfectly.
