I used a spray degreaser and a stiff bristle brush and then finished with rubbing alcohol on a paper towel. **Q: Is this applied inside or outside the smoker?** A: Either one would work. The best application is inside the smoker so that the sealant isn't seen from the outside. **Q: would this seal on a granite counter top joint?** A: As a contactor that lays counter tops I'd use a non-sanded grout with a latex mixing compound. It shouldn't take much. **Q: Can it be used to adhere silacon feet to the grates of a cooktop?** A: It should work fine as long as it is not expected to actually provide support. ## Frequently Bought Together - Silicone RTV 4500 FDA Grade High Strength Silicone Sealant, Black (2.8 fl.oz) - Dyna-Glo DGO1890BDC-D Wide Body Vertical Offset Charcoal Smoker,Black - Dyna-Glo DG1890CSC Premium Vertical Offset Charcoal Smoker Cover Black --- ## 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/577699400-silco-incorporated-silicone-rtv-4500-fda-grade-high-strength-silicone](https://www.desertcart.tn/products/577699400-silco-incorporated-silicone-rtv-4500-fda-grade-high-strength-silicone) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-10*
