Hi Everyone,

What started out as a "simple" project to replace the center speaker in the dash has turned into a full-on interior makeover. I mean pulling out the seats, carpeting, dash, heaterbox and A/C unit, and replace the original wiring harness on my 1972 Cutlass Supreme Convertible.

As I start to prep the floor pan for paint I have this black sealant material that is used to seal metal seams and my guess, prevent moisture from entering the interior of the car. Please refer to the attached photos.

What is this stuff and where can I get it to replace the old and cracked material I'm removing? Is there a modern version of this material that I should use? Thanks for the help.

Cheers.

 

I used the Eastwood Brush on Seam Sealer.

 

Please don’t be offended, but I laughed at this. It’s a convertible. Moisture has other ways of entering the passenger compartment. But as Norm said, seam sealant is the stuff.

 

I am wondering if he can stop the MAW before the body comes off the frame.

 

Unlikely. Having the inside nice and clean and purty means ya wanna have the opposite side equally nice and clean and protected. Gotta pull it. :-D

 

No offense taken. Why do you think I pulled the A/C and heaterbox? I'm live in Southern California, I don't have a need for either of those. Thanks for your reply.

 

I’m envious that you don’t need AC. Summers here get to 115+ and before living here I was on the Gulf Coast with brutal humidity year round, so AC has always been a necessity for me.

And one reason why I laughed was when living on the Gulf Coast there were numerous thunderstorms that caught me with the top down and practically flooded the interior of the car. One time I got home from the grocery store, carried the bags inside, and when I walked back out the rain was just stopping and there was like 5 gallons of water in the folded down top. I had to bail it out before I could raise the top. Having a floorboard drain would have been a plus.
