I used the Proform PF 7773, it was $40 a tube compared to the 3M which was $75. I bought a couple tubes thinking I'd use them all, but turns out it lasts a while, I only used 1/4 of the tube on the whole upper section. I'm thinking I'll use the adhesive along the trunk extension and possibly on the wheel arch, and spot weld the door jamb, the tail light area, and under the rocker.
