My roof was recoated with EPDM rubber roof in a bucket three years ago. No problem thus far. **Q: Has anyone used this on galvanized metal roofing? Lots of seams!! Some have been caulked with silicone..** A: I used this sealant on a galvanized camper roof at the numerous seams that were previously coated with silicone. I made sure that I centered the silicone with the sealant. I was worried but took the chance that there would not be a reaction between the two products. it has been two years now and the roof is still fine **Q: What size is the roll of tape** A: The tape is 4 inches wide by 50 feet long. There are three sizes to choose from, 2" x 50' long, 4" x 50' long or 6 inches wide by 50 feet long. It's designated on the packaging as 2-50, 4-50 and 6-50. Works great. You can put it on and done! When you use lap sealants by Dicor or other makers they take up to a month to fully cure. **Q: Would this be good for a large mobile home roof ?** A: I think it would be good to use on any camper or mobile home roof to help stop a leak, especially at a seam, but it would also be a good idea to seal around the edges of the EternaBond with a bead of DiCor sealant. That's what I did on my aluminum camper roof and it worked like a charm. ## Frequently Bought Together - ETERNABOND RSW450 - Thetford RV Toilet Seal Lube and Conditioner - Toilet Seal Lubricant - 24 oz 36663 - Valterra T58 Twist-On Waste Valve, Mess-Free Waste Valve for RV's, Campers, Trailers --- ## 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.sn/products/1889802-roofseal-white-4-x50-microsealant-uv-stable-rv-roof-seal](https://www.desertcart.sn/products/1889802-roofseal-white-4-x50-microsealant-uv-stable-rv-roof-seal) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-18*
