i am in the process of replacing the rear end of my MK2 golf
i bought the new panel from the stealer, i drilled all the spot welds and pulled the old bent and rusty panel off, i am getting ready to weld it all up
but
what do i do about the seam sealer that is in the vertical seams under the bumper
when took it apart it was litterally glued together there (the welds are actually more inward)
do i put a bead of seam sealer like caulk before clamping the panel in place and welding ?
what seam sealer should i use, where do i get it?
(i'll need to buy alot as i have chiseled out the sealer on most of the seams of the car for stitch welding)

Re: replacing sheetmetal (gillano)

it's not seam sealer, it's panel bond adhesive. run a bead of panel bond before you clamp and spot weld the new panel on. then, after its cured, use a seam sealer to... well... seal the seam. http://****************.com/smile/emthup.gif
but basically, seam sealer shouldn't be between panels.

Exactly. You could use 3M 8115 between the panels to make it ultra strong. buff to bare metal the areas where the panel makes contact with the car (on both the panel and the car). Then spread the 8115 to cover all the bare metal on both surfaces except where you plan to spot weld. Clamp it on so it doesn't move and weld it. 8115 has a 90 minutes work time so no need to hurry. That's how we do in our shop. Uber strong and the 3m stuff seals everything.
