Also known as armor plate, these 5083 aluminum sheets are hardened to an H131 temper for increased strength and impact resistance over standard 5083 sheets. Choose-a-Color 5005 Aluminum A black, gold, or silver anodized finish protects this 5005 aluminum from wear and abrasion.

I used that wax paper backed aluminum tape that comes in rolls and is sold for taping ducting to seal the seams of this stuff. The floor section of my car is made up of at least a dozen separate sections so that it follows the contours of the floor. Once taped, it acts like one form fitted sheet of Insulator.
