Even as I wrote it I knew someone would call me on it <g>.  That's why I
added the phrase "per application."  I think probably one good application
of properly applied mat will provide more strength than one application of
cloth.  But you are certainly right that ultimately mat is not the strongest
material; multiple layers of cloth will give more strength.

Also, I completely agree with Erik's comments about skin sensitivity.  I'm
probably a little too what-me-worry? about the whole thing.  I keep gallons
and gallons of acetone around and use the stuff like water.  But I have been
told that epoxy sensitivity is a nightmare if you have it, and why take
chances.  Thanks for the clarifications, Erik.
