I'm going to be using the 3M automix seam sealer (2-part epoxy) and then a layer of lizard skin. My current plans are to put lizard skin on everything except the roof panel. Since I'm replacing the roof anyway I thought I would use dynamat on the roof. With a hopeful relief from the brutal heat, I hope to get back to finishing the rear sheet metal in the next couple of weeks and get the car on the rotisserie for the sealer. Hope this helps and good luck!

What about 3M All-Around Autobody Sealant Caulking Tube?

As a body man I would recommend a two part sealer. I would shy away from the single part ones. I know people will argue that ones better than the other but with the two part ones there is a chemical reaction that dries it. Whereas the one part air dries, and to me will continue to air dry until it is hard and brittle. Then be prone to cracking.

Just my .02

Usually one tube will get it done,as long as you don't get crazy with it. Make sure to prime any bare metal before applying seam sealer .

I used different types of seam sealer for different places. I used non hardening seam sealer on the seam at the rear quarter to the panel below the rear window, I applied an amount that was more than needed and let it sit for a week and then trimmed it with a razor knife flush to the body and then used epoxy primer over it. I have gone over 11 years with no cracking.

Seam sealer that gets hard will always be prone to cracking and should only be used in areas that don't flex. But to each his own and everyone has their way but I followed the guys who didn't have problems.

I used 3M
