[NSRCA-discussion] Reparing a de-laminated ARF wing

[Ed Alt]

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?

Thanks

Ed
