I fiberglassed the left side of a rudder once, sanded it down nicely, and then glassed the same side again.....duh

I also put a 3" piece of red Monokote trim on the end of an aileron on a pattern plane. Flew the plane a while, and then sold it to a friend, who flew it several months, and then at a contest noted that the trim was lifting......lifted real easy with the backing still on....amazing that it stayed on as long as it did! I still get kidded about that, and it was like16 years ago!
