Guys,

My 2007 Avy had major leaks between the bed panel seals, especially during car washes.
Everything in the bed area was getting soaked.

I ordered the two bed panel seals, Part # 88944066 from GMPartsCenter.net.

Both seals, the one on the front of panel #2, (the center panel), and the one on the front of panel #3, (the rear panel) are the same part, and same part number.

The parts were $93.70 each, handling $8.95 and free shipping. Total $196.35.

It is bone dry now...!

We had torrential rains all night......no water inside at all.

These are factory GM parts.

The old parts pulled right off, I cleaned off the plumbers putty that was holding the seals on the panels. squirted  a bead of automotive trim adheasive right on top of the new bead of putty that comes already in the new seals and seated them on the panels
I let it dry for a day and installed them.

Success!

I should have mentioned, the adhesive was 3M Black Weatherstrip Adhesive, from an automotive paint supply store.

It didnt take much, and was $8.00 per tube.

I just didnt trust plumbers putty.
