It's made of .050 6061 aluminum. It's light yet still strong enough to not flex when installed. I recommend applying a bead of silicone around the perimeter to seal out any fumes from the engine compartment. Each panel has a sanded look finish. You can paint it to match you car's color. This panel will fit 93 through 02 F-bodies. I plan on making panels for more cars/trucks. If you have a current project. Preferably the heater is already removed. I'll give you a finished panel for free if you let me make the template from your car.
