Just Cool It! Is it getting a little warm in the cockpit? Cool-It insulating mat from Thermo-Tec is the solution. Fabricated from a resin-bonded silica blanket sandwiched between a mylar and foil facing, this mat reflects away heat and keeps you and the rest of the car cool. Not only does this insulation mat protect against the heat but it also serves as a sound absorber. Apply Cool-It mat to floor boards, firewalls, transmission housings, or anywhere heat may cause a problem.
