Was wondering if finishing resin could be used instead of regular epoxy.  Anybody ever done it ?

Allen,

Your answer is right under your nose.   Go to the top of this sub-forum and read "Molded Leading Edge Caps for foam core wings" by Bob Hunt.  Modeling information does not get any better than this, so be sure and take advantage of it.

And a big thanks to Bob for taking the time to share his warehouse of knowledge with us.  It doesn't get any better than this.

Cheers.
