UHU should work just fine for all construction. Sanding off the paint won't hurt, but Goop will penetrate into the voids and adhere just fine over the paint. But err on the safe side and sand off the paint. One less thing to worry about in flight...

| thank you very much, im a total newbie on this....appreciate all the patience given... how about the balsa/plywood to EPP on the wingspar will uhu or goop be a good glue for this joint or should i use epoxy on this? Also i have to glue 2 stiffiner blocks 1ea on each side of the fuse, the fuse has some paint design on it. do i need to sand the paint off before i lay a coat of UHU or Goop? Thanks much.... | |
