Cowl Heat Shields

Time: 2 Hours

Once the lower cowl was sealed with the Rhino 9700 I was able to start adding the heat shielding. The fiberglass is close to the exhaust pipes and the heat they produce. Untreated and the cowl can heat up enough to to bubble the paint on the exterior. There are various products one can use to shield the cowl from heat, I used a product called Thermo-Tec which is a 12” x 24” adhesive backed liner that consists of a fireproof material covered in a foil like reflective material. I started with a couple of paper templates that I taped to the inside of the car and put it in position with the engine. I made several changes in order to make sure I had good clearance on either side of the exhaust pipes on the left and right side of the engine cowl. After I had that complete I use the templates to cut out the shapes and the actual material. Are used some denatured alcohol to clean the newly sealed cowl and applied the Thermo-tec material after removing its protective back layer. The adhesive allows for you to move it around slightly before applying pressure to make it stick permanently. It is also easily manipulated around complex curves and corners. The last thing to do is decide how I want to seal the edges of the Thermo tech material, either with aluminum tape or high temperature RTV.
