Hysol - yes, works very well, very convenient and very neat.

Reason I asked about testing is that I have worked with polyester and epoxy a bunch, but not vinyl ester. Some of these planes coming over have a smell that I would associate with polyester (maybe vinyl ester to?) and not epoxy. Smell's not too accurate though; would be better to have a chemical test or something to be able to be "objective".

I think Ronnie was right, but I'm not certain ALL Feiba (sp?) jets are polyester, though I highly suspect a few are that I've seen.

Has the quality of polyester resins improved? I know the vinyl ester resins are supposed to be much better.
