f5fstop!!! Yes!! You were right! I printed the GM/Hummer bulletin you had posted and drove down to the Hummer dealer today. Spoke to the Service Manager on duty .. he read the bulletin and asked if he could keep it ... then looked at the two air intakes vents/boxes AND the strip under the windshield/windshield wipers. He said the marks were DEFINITELY water marks caused by the Wrap Guard. OMG! I told him the service writer told me the marks were left by 'bird poop'. I keep the truck clean 24/7, so I knew it wasn't from 'bird poop'. He shook his head and said no, there are definite water marks .. and that the clear coat looked to be coming off in one area. I was livid since they kept the truck for so long the last time for the other prob. He offered to put me back in the Escalade again (AGH!) .. I just turned it in yesterday. Told him no .. I had already forgotten what my truck looked like. So, he's ordering the whole section (both air intake vents and the strip under the windshield wipers) and will call me for installation when they are all set and ready. They'll put me in a loaner for a day while they do the installation. THANK YOU SO MUCH for posting your thoughts and the bulletin! If I didn't have it in hand, I don't think he would have done anything. Thanks f5fstop!!!!!!!!!!!!!!!!!
Also, one of the mechanics told me to buy some 'Armadillo' at Pep Boys (or similar)for the small discoloration spots on the vinyl strips that go up the A pillar. He said that should work them out.
