I have used this material on 2 of the Carbon Cobras. I have it on the foot boxes, floors pans and tunnel. It is thin and very effective.
We also made a heat shield to protect the clutch master cylinder from the under car exhaust (only inches away). The side with material on it was 380 degrees while the master cylindr side was 105. Not bad considering it was 102that day. I highly recommend it.
