Looking for something to line the inside of the cabinets in my Motorhome ti help with heat** A: 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** A: 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: Does it not release any smell or odor what so ever, if parked outside all day in the scorching tropical heat from the Caribbean?** A: unfortuanty I have NO IDEA how hot the Caribbean sun gets.....We never noticed qy smell ... **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.** A: 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. ## Frequently Bought Together - Siless LinerPRO 2in1 200 mil (5mm) 36 sqft Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener - Car Sound Deadening Roller Metal Installation Tool 3 Pcs for Auto Noise Roller Car Sound Deadener Application Installation Tool Rolling Wheel Interior Accessories - Siless 80 mil (2mm) 36 sqft (3.4 sqm) Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (36 sqft) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/415379038-siless-linerpro-2in1-200-mil-5mm-36-sqft-car-sound](https://www.desertcart.tn/products/415379038-siless-linerpro-2in1-200-mil-5mm-36-sqft-car-sound) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-09*
