Default need part info to fix trunk leak

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.

Same thing happened to me about a month ago. I have an '04 that I purchased in the beginning of August this year. I was chasing down a rattle, pulled the spare tire and found the same thing, about 3" of water in the well. I wet vac'ed it out, dried everything then made an appt with the dealer. When I described the situation to the service manager he didn't seem to surprised. This is what read on my invoice:

Customer states that the spare tire was submerged in water.

Cause: Repair open body seam in trunk area
B5410 Reseal lower body seam in trunk areas
35 W94

Hope this helps, good luck!

If under warranty still, maybe. If not, no way. Not a TSB/Recall item. The GXP is known for leaking in several areas that cause the spare tire well to flood. Sealant misapplied, crappy rubber seal comes off/dislodged in back easily, and a few spoilers missing rubber washers in assembly.
