Am I Crazy?

There are all sorts of spots like that on the '65, '66 cars that weren't primed or painted. They only designed these cars to be driven for seven years, not forty! The cowl is the most obvious non protected part.

hey i did the same thing but i just took a wood chesial?? took me awhile but then i repainted it with some flat black... i had some paint left of mine is some spots but the rest i think jsut came of when i took the under coating off...

Sometimes you have to do what works. The whell wells on mine had an 1" of undercoating and etc that had been built up in it, I took a chesial and went to work.

You either use the blue knife or paint stripper to remove the factory undercoat/sound deadener. I chose the same method as you. To attempt to recreate it--I plan on using a 3M body Schutts gun to recoat it with chip guard coatings, then paint over it with semi gloss black.

I'm not sure what the big deal is Not that I've seen a lot of undercoating on cars in this neighborhood but I remember the '76 Gremlin Mrs StDr had inherited from her father and was still driving when I met her - he'd had enough "Ohio-proofing" shot under that car to make it about 1/4" or more thick! Car weighed half again what any other Gremlin would have weighed. I had to scrape a bunch of it off to the frame-rail-mounted fuel filter he had also installed.... stuff look a heck of a lot like the hot-patch tar used to seal shingle roofs. Lotsa times, I've seen that stuff heated up with a flame-thrower so the roofers could peel back the asphalt sheeting without tearing it around the seams.

Sounds like a very simple plan to me - although you might want to look out for any frame-mounted fuel fittings that are still "wet" BOOM
