: Beige Goop in Trunk

02-11-2004, 07:19 PM
Upon wiping down my car from a quick high pressure wash, I riased the trunk to wipe it down--found some beige goop dripping from the left assembly that lifts the trunk up and down into the carpeted trunk area. Will have to have dealer clean since the stuff got real hard immediately and caked onto the carpet.
None noted on right side--anyone experience this or have any ideas what it is?

No, have not seen anything showing up in the truck post having washed at the dealer or by hand at home. But then I have never use a pressure washer to wash any of my vehicles. But then that should not generate a liquid goop that sets up hard shortly there after.

The only thing I noticed is that if the trunk lid is wet and you open it, it drips water into the trunk. Now I always dry that area (the front-most side pieces) well before opening the trunk. No big deal really.

Have you learned anything more about your "beige goop" the trunk? The only thing that comes to mind is that the color an oil and water mixture is beige or whitish. However, the trunk and roof mechanics are electic not hydraulic. However, there is lubricant used that might be mixing with the water from washing. Just a guess.

will be bringing into dealer soon--and will advise-
Since I am in the windy city not any chance to use the top yet but lots of hope spring will be here soon--so problem has not increased--also need to get my lights adjusted downward==and have a small vibration at 60 or so from area near inside rear storage area

I look forward to what your dealer discovers is the problem with the goop.

As for the vibration at 60 MPH I've heard from one other XLR owner that had the same problem that was fixed by replacing the half-shafts, which are the drive shafts between the differential and each rear wheel. You may have something different, but thought I would mention one known problem/fix.

The white very sticky "goop" is a sealant that is installed by CTS Car Top Systems the company that makes the Aluminum/magnesium folding hard top for the XLR & the SL 500.

The material is similar to beutyl caulk that is used to hold/seal winshields in place. The material is the secondary water barrier preventing moisture from getting inside the XLR. When CTS Inc. produces the top the White adhesive/sealant may have accidently put a little too much on any given top structure.

To remove the sealant from any surfaces you can use traditional rubbing alcohol. You can clean the surfaces around the weather strips though don't raise them and clean under them. Use the alcohol to clean it off the carpeted area if any has dripped in to the luggage well.

Thank you for the extensive insight for the problem at hand. I am very familiar with the sealer you referred to. How many other reports of this are there? It really seams strang that this is the only event? However, assured is one in following your recomendations.
