Review: Five Stars - Graet Product Ever!!!!.....
Review: Great Product - Used a total of four cans on my 96 Cobra. I did the floors and trunk after I gutted the interior panels to dead out some road noise. Worked great for me. A pointer that if you have drain holes in the floor or trunks make sure to seal them then spray, if you don’t the road noise will still be evident.
