I've never used epoxy that was too thin when wetting out cloth for vacuum bagging. Less epoxy is generally better provided it has suitable mechanical properties. Now if you're just gluing things, then epoxy can be too thin.

Hi all,
We'll looks like the lively discussion is dying down which I started by
indicating I'm going to scratch the Multiplex EVO from my list and who sells
the Multiplex 4000.  Actually, the discussion was a benefit to everybody on
this list. I do own some JR stuff, XF622, X388S, 10SX and a 10X. One Vision
and one Hitec, but when you want to set them up your own way, you run into
the "you can't get there from here thing".  So my next one will be a 4000 !!

Now here's another request from some of the knowledgeable people out there
on epoxy for vacuum bagging or epoxy in general. When I start looking for
another source of epoxy, I look for their Technical Data pages. My question
is does somebody have a web site, or information explaining (in layman's
terms) just what those technical properties indicate to help me or anyone
else evaluate which may be the best choice of epoxy from the various
manufactures I consider.

PS I did receive an answer from System Three on their Clear Coat epoxy.
It's generally too thin for vacuum bagging for our wing skins, but would
probably be OK for the discus launch gliders which use minor amounts of
laminating epoxy in their construction.
