I'm working on re-covering my Skybolt and I'm fixing a few issues on the way...

On the bottom wing, where the wing seats in the saddle, the sheeting and leading edge are "wearing" and have some good grooves in them. I am replacing the wing sheeting in this location (because of the wear and because some of it is fuel soaked) and would like to reinforce this area. I was thinking of using some light fiberglass. to strengthen it and slow down the wear in this area. Will this be too brittle? Any other thoughts or ideas?

Thanks,
-Todd
