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.

Terry, I've noticed after crashes that anything less than 1.5 oz FG cloth doesn't have much structural value. I don't know how a dryer sheet compares to light weights of FG though.
I built a few of the 40 inch span Randolph type 1/2A planes without any FG cloth anywhere and they were plenty durable.

It is pretty much like silkspan. Did you use polyester resin, or epoxy?

Tewitt--- I have been using used dryer sheets for years, they work great. I stumbled on to using them one night when I could not find my glass cloth, and needed to patch a cowl. It worked great

I use a thin coat of epoxy, I have also used ca. I like epoxy better because while the epoxy is soft, I take the plastic off the back of mono coat and lay on the epoxy and smooth it out evenly with my finger. After the epoxy is set up, yank the plastic and it will come right off leaving a smooth finish. The epoxy has to be set hard.

For wing roots, I've used old covering inside out over the reinforcement (epoxy + whatever), and taped at the lap seam.Then I shrink it with the heat gun from the center out. Put some masking tape just outside the covering zone, and wipe up any oozing epoxy. Poor man's vacuum bagging.
