I know how a KR2 wing is miced. I bought a KR2 that had been built in the 80's & decided to redo foam & glass on the wings someone had added an other layer of glass & I think they used polyester over epoxy . When I opened up one wing there were 2 very desicated mice when the wing was built they must have living there & when the wing was closed up that was the end. Must have been there for 20 years.
