Waterproof and creates a tight seal. Clean white looks great, higher price than caulk or silicone but for this application I think it’s a good value for the money. Used it install a new roof vent on inclosed trailer. ### ⭐⭐⭐⭐⭐ Easy to apply, holds up well so far *by on Reviewed in the United States December 17, 2025* I can't give you a scientific or long-term review of this stuff, but I used it for the first time a couple of weeks ago just to reinforce some weak areas with the previous sealant had bubbled up and broke or cracked. Yeah, it's more of a band-aid application, but it went on easily, had just the right viscosity to spread and level without going too thin. I gave it a try because it was a bit better price, but it seems to be a fine product.Between then and now, it experience rain, sun, and cold, and went on a 200-mile road trip. When I checked it yesterday, it looked exactly as it did when I applied it... smooth and bright. So, I can't speak for long-term durability, but so far, so good. When I do a more thorough job, I will order this same stuff again. ### ⭐⭐⭐⭐⭐ I recommend it *by on Reviewed in the United States August 27, 2025* Yes works great as advertised happy w/ the results --- ## 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.us/products/204061604-rv-roof-lap-sealant-self-leveling-epdm-caulk-for-rubber](https://www.desertcart.us/products/204061604-rv-roof-lap-sealant-self-leveling-epdm-caulk-for-rubber) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
