It has been raining for a week in Missouri, so I took advantage of the foul weather to finally find my GXP trunk leak.
It is coming through the lid weatherstrip at the latch area. Here'* why it'* leaking....
That very hard tar-like seam sealer that GM uses at the body seams is slopped all over the lip and has caused the weatherstrip to be deformed and doesn't seal correctly.
I will need to remove the weatherstrip. Scrape or chisel off the seam sealer in that area and then replace both correctly.
I need exact part info for the weatherstrip adhesive and the body seam sealer.
Bone-evil did a write-up with several part numbers when fixing the applique, spoiler, and CHSML. His info stated:
Dominion Sure Seal, Sure Solve, Kent Acrosol, 3M Clear Auto Sealer, and Silicone Rubber Sealant
I'm not sure which of these (if any) would apply to the weatherstrip and body panel sealer. Thanks for any help.
EDIT: I don't know how I got this in the GXP section, I meant for the 2000-2005. Mods may want to move it, it applies to all those models.
