Roger,

Has anyone here thought of or used this product?

I've never bought it or used it in a product, but the manufacturer sent me a
sample to try. The first thing I did was hold a lighter under it. As soon as
I saw how it smoldered and smoked, that was all I needed to know it was not
for me.

The danger of fiberglass is greatly overstated. Yes, you can get a little
itchy working with it, so use gloves and a face mask. Problem solved.
