kelleherdl, could you find out what the thick stuff is he is spraying? This may be what I as well as several others are asking about am searching for.
Thanks everyone for the information. Strange, but I had to remove all of this stuff from my car, but never realized what it was until I watched Grave Yard Cars last night. Even though there is a bunch of junk and very little car work, you just may learn something every now and then.
