Now you can get the same high-performance materials used in today’s automobiles. Now it does not have an OEM look, if you have an original car Shark Skin may not work for you. The black scrim face will work in any engine compartment. Very nice ‘finished’ look to compliment all your hard work. SharkSkin is 2.5 times denser by weight than the ‘ repop‘ type insulation. This is GREAT heat insulation and will help to absorb engine compartment noise. It will not slag or fray. Our hood insulation is shipped flat, not folded & crushed. SharkSkin can be glued in place, 3M Super Trim Adhesive 08090 is recommended. Readily available at most local parts stores.
