<DIV>Thanks for the tips. Actually, it's not a botched repair, it's an ARF
wing that came this way. I agree about the poly-U pressure being a
potential problem. It would require having the original shucks or
something close to it. Maybe it would work with some other foam shucks and
placing a towel or something in between to fill the shape mismatch?</DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [NSRCA-discussion] Reparing a
de-laminated ARF wing</DIV>
<DIV><BR></DIV>
<DIV>I'm looking for a good method for repairing an area of of sheeted foam
wing where it is not fully adhering, roughly 30 sq" in area. Current
thoughts are to try to inject some polyurethane glue just under the surface,
maybe a laminating epoxy instead. The tough part seems to be how to
get sufficient coverage right under the skin without going too deep.
The wing is already covered and I'm thinking that one method might be to use
a suction cup and gently pull the skin away to assure a gap so that a needle
would get the glue in between. Any thoughts on this?</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
