Powertoys- that's what I covered mine in-Koverall and dope. It looks like it would be heavy as hell when you put it on, but after the stuff cures, it's surprisingly light and tough. I've gotten to be semi-expert at repairing mine, mostly runway rash on the wingtips, NBD, but most recently (Past Dec 1st), I had a severe stupid attack and forgot to hook up the aileron servos (I was running my mouth to my flying buddies). I got to see what it was like to fly a Cub without ailerons (to make it worse, one was at about 15 degree right bank) I managed to keep it right side up until I got back to the runway, and stalled on my approach, it hit on the mains and chin and the impact tore the wings off at the root (pulled the end rib out on both of them) and cracked the angled uprights along the sides of the windshield. Took about 2 weeks to fix, but you really have to look hard to see the repair. That's one real good thing about the Koverall, you can dope it on and the edges blend right in. I started out with the plane at 9-1/2 pounds, it's probably past 10 by now, still flies great. The .65 saito just putters by, I've got an older style billet aluminum muffler on it , sounds great
