Here are photos of my Golden Hawk.  It started in life as a Blackhawk kit, but I modified it to match the original design as produced by Scientific.  Sadly, that beautiful looking finish and decals will have to come off and be redone because I mixed the red epoxy wrong, and it won't harden up.    

Larry,
That is a really good looking plane. It is unfortunate that the finish won't harder. Before going to all the work of refinishing, try heating the finish. Epoxy, even when not properly catalyzed will often harden when heated. If the other half will let you, put it in a pre-heated oven at around 150 to 200 deg. F. Start at the low end and increase (not with the plane in the oven as some use the broiler element to heat the oven... no infra red just heated air) it if needed. You haven't got much to loose and it may just work.

     Larry , leave it in a hot car with the windows up , better than your wife catching it in the oven !

Done that!
It works, in Florida. Our closed cars, in the sun, get into the 120's.
I measured same.

Not on purpose, but hot car, 2 hours, wrinkle finish!  Wierd!  Wonder if it will reduce drag like a dolphin's skin?

But did it cure the epoxy?       

Guess: The wood expanded while the epoxy started hardening, then cooled down and contracted as the epoxy finished hardening.
