Here's a couple of suggestions. The leading edge could be made from Balsa wood. Coat the inside of the balsa wood cove with a sanding sealer to close the grain. Then, attach the the balsa to the aluminum flap with contact cement used to attach counter top laminate. Sand your final shape in the balsa then coat with varnish. When you cover the aileron in fabric and shrink it down the fabric will help to hold the balsa in place. Balsa has been used as fairing material for a hundred years so it should work on a Super Cub just fine. Just my thoughts and ideas.

What do Just Aircraft use for gluing the wood ribs to the aluminium spars?
I bonded the redwood cove on with West Epoxy and microballoons, placed the parts in a big vacuum bag, and trimmed off the excess. Here are the results.Does anyone know the washout for a PA12 aileron?DSC00266.JPGDSC00247.JPG
I wound up using epoxy and microballons. It worked well. I then trimmed and sanded to the desired shape. I am happy with the results. I also used a metal shrinker to form the trailing edge instead of the piece
of tubing for the curved tip section.
