Anyone (besides me & Joel ;-) remember G. Matthew Bulley and his
Heat, Rust, Noise project on an '76 bus?  He used Kool Patch
extensively in the inside and as undercoating.  Here's a link
to a message of his in May '98:

In fact a google search for "gmbulley kool" gets his pages:

BTW--is he still lurking on the list?
