An interesting question.

I found the Material Safety Data Sheet, at
http://www.fiberglasssupply.com/Misc...MSDS/msds.html

The ingredients a
Bisphenol -A type epoxy resin 50%
Bisphenol -F type epoxy resin 20%
Benzyl Alcohol 20%
Ethylene Glycol Monobutyl Ether 0.03%

If you look at several of the other products on that sheet, they share
many of the same ingredients.

I know it is something to do with epoxy .. but what?

Is this just a brand?

Also,,, if you need fiberglass supplies when fixing an old sailboat, where
would you look? Do you go to an auto repair supply place?
