Today I found these two small blocks of sticky things on one side & the other side looked like aluminum foil under my car, & was wondering what they were, I thought I ran over something and it melted on the undercarriage, however it seemed like they belonged there. Can anyone help?

They are part of your car they were put there as an anti vibration buffer according to my GM dealership. Hope this helps

They are a dead soft aluminum foil bonded to a viscoelastic polymer sandwiched between an isolation pressure sensative adhesive backing.

Vibration in a panel will be transferred and isolated by the elastic properties of the polymer and deadened by the aluminum.

It is usable in a wide range of temperature and has very strong resitance to the elements and solvents and cleaners. It was developed for the aircraft industry and has been used in the auto industry for several years.

Those things just look out of place. I now know what they are suposed to do. Who knew?


This is exactly why this forum is the center of all Corvette knowledge.

i was curious as well

dealer told me they can replace it but i dont want to leave it in for half a day and risk them cracking my rocker panels!

are these pretty easy to buy at the parts counter or at any autozone/pep boys?
