Siless LinerPRO 2in1 200 mil (5mm) 36 sqft Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener

Siless LinerPRO 2in1 200 mil (5mm) 36 sqft Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener

Q: Can you paint the outside of this product? Looking for something to line the inside of the cabinets in my Motorhome ti help with heat

I would not paint it. It is a sponge foam. The lighter 80mil would be better to paint with the aluminum backing. Be sure to use high heat paint

Q: What vwlse should bebused with b this

I used fiberglass suspended ceiling tiles. They are somewhat rigid and easy to cut to fit. They hold their shape better than fiberglass bats will over time in a shaking, vibrating vehicle. Styrofoam will squeak and drive you crazy.

Q: Do they have an unbranded version? considering a product like this for a jeep hard top and would much rather have a solid black appearance.

The fiberglass is yellow and the plastic covering on all of it I've seen is white/off white. I believe you would need a thin plastic or cardboardy headliner. I haven't used this on a jeep.
