Rubberized Undercoating

["doug armstrong" <darmstrong@ptbo.igs.net>]

A friend of mine located in Ontario, Canada, manufacturers heavy trailers,
for construction equipment, etc.  He is looking for manufacturers of
rubberized undercoating.  He wants to purchase it in 1 gal. or 5 gal. pails;
not in aerosol cans.

Any suggestions?

Thanks
