GM TSB for leaking "T-tops"

I'm going to try this before replacing t top weather stripping.

CONDITION:

Water leak in roof area between T-Top opening and rear hatch opening. (T-Top vehicles ONLY)

NOTE: This condition may appear to be a leak at the T-Top weatherstrip. It is advised that this repair be performed and tested on T-Top vehicles with leaks in this area BEFORE any other repair is performed.


CAUSE:

Spot weld burn-throughs in rear hatch gutter area between hatch hinge attaching points.

CORRECTION:

Seal weld areas as follows:

1. Open hatch.

2. Compress hatch opening weatherstrip to improve access and apply a thin even coat of 3M Clear Auto Sealer (3M #08551) or equivalent to hatch gutter area between hinges with a small brush. Avoid getting sealer on weatherstrip. Weld locations should be given slightly extra material if possible.

NOTE: Some weld flash may exist near some of the spot welds. This flash is sharp and care should be taken to avoid injury when determining the location of the welds using the fingers.

3. Close hatch.
4. Follow sealer manufacturers recommendation for dry time and test area by running a large amount of water over area. Due to the small size of the burn through holes, the water test should last at least 15 minutes.

Ayone tried this? I did and it fixed mine. I was hoping someone else would benefit from this.
