The body shop removed the insulation from the inside of the hood when we got the BMW painted. I didn’t think about how hot the hood got until I was covering the car the other night and put my hand on the hood. Jim Stansfield at Mesa Performance sent me up some insulation that wasn’t too hard to put on. I made a paper template from the cutouts in the hood and traced that onto the insulation. I cut the insulation with household scissors and used 3M Super Trim Adhesive (for garnitures). The glue is a contact cement that is applied to both surfaces then joined.I finished the edges with silver foil aluminum tape. It’s all kind of shiny.
