Glyn44 Posted September 28, 2017 Share Posted September 28, 2017 Quick question please. If I fill the groove/slot on the elevator joiner with epoxy, which I then intend to sand to profile, will my heatshrink covering adhere to the epoxy ok?

Denis Watkins Posted September 28, 2017 Share Posted September 28, 2017 No Glyn, it is a bit like grease proof paper, it just doesn't stick. I had some success with balsaloc, applied hours before covering, so it had completely gone off, but you could still see the line Quote Link to comment Share on other sites More sharing options...
Glyn44 Posted September 28, 2017 Author Share Posted September 28, 2017 Cheers Dennis, I guessed it would be a problem. I'll think of something else. Perhaps epoxy down the hole, and PVA to fill the groove orneven leave it open and just over cover the open slot. Thanks again. Quote Link to comment Share on other sites More sharing options...
Trevor Crook Posted September 28, 2017 Share Posted September 28, 2017 It's a long time since I did it, but when I used to join foam wings with epoxy and glasscloth, I used to cover the epoxy in masking tape, which seemed to do the trick. Don't know if that would work in your application though. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted September 28, 2017 Share Posted September 28, 2017 Make the film overlap long enough to reach the wood above/below the joiner slot, it won't matter that it's not actually adhered to the epoxy as the film will be bonded to wood either side of it. When you cover the second side (top of the elevator?) the film will be bonding to the overlap from the bottom covering. It's worked for me on countless models. Alternately just don't cover the slot then seal the film edges with a smear of epoxy extending across the joiner, it's usually out of site in the elevator hinge line and I doubt anyone will notice.

Engine Doctor Posted November 13, 2017 Share Posted November 13, 2017 Old thread but if you are interested still you can paint the sanded epoxy with Clear coat fuel proofer before covering and allow to dry. the iron on covering will then stick to the epoxy like **** to a blanket.
