........WhaT type of fiberglassing resin did you guys use?................
==============
I use Minwax water based polyurethane. It's one heck of a lot less trouble than resins or epoxies, not to mention less smell. Get it at Lowes/Home Depot, etc. I've used it on my Herk, the OV-10, and am in the process of glassing the B-24 with it.
