It would take 2 or 3 cans of the 3M seam sealer to do a B-body Mopar. It's a pain in the rear to apply, and shrinks a lot as someone else mentioned.
The best stuff that resembles the factory sealer is from Wurth. It is easy to apply with a 1" diameter brush and leaves the brush marks looking factory without shrinkage. http://www.wurthusa.com/web/en/website/p...rsfinishing.php
