I don't know how many guys use fiber glass stuff on the wing joint, but I've never liked how think it looks in the middle. Then one day I picked one of my wife's bounty dryer sheets and then it hit me. I could use one of those instead of the thicker fiber type mess wing reinforcement stuff you buy.

Anyways, I tried it and it seems to work great. You can't hardly see it when done. It probably wouldn't make a lot of difference but its probably lighter in weight also.

Just thought I'd pass it one.
