I am curious to know what that c-channel anti-squeak/seal material was actually made of. It was used on the firewall/fender filler panels, under the dash above the heater hole behind the inner cowl, and on the rear section of the inner fender. Seems to be a lot of engineers posting on this site. Any of you guys chemical engineers, or do you all drive choo-choo trains. (I'll bet you guys never get tired of that line.
