A easy to use version of the asphalt undercoat used in late 60s and 70s cars

Good stuff but very messy. Wear gloves and cover all skin with clothes you don't want any more.

I used this for the wheel well of my truck for sound deadening and just for protection of the undercarriage . It goes on easy and only needed 1 coat ! Looks great and will use more in the future !

Perhaps I should have read the description more carefully. The white lid is deceptive. The product is black.
