It sealed easily and was black to match the unit etc. Went off fairly fast and has remained ever since doing its job - Sealing. Cheap, easy to use and very effective. A1 Product ### ⭐⭐⭐⭐ Black, easy to apply, can be messy *by B***R on 21 May 2020* The price is good and delivery was quick. The sealant tube is as easy to use as any other sealant tube (though you'll need to provide your own nozzle). Adhesion is good but not great, so you can get some stray blobs, and with the black dye those blobs can soon make your clothes a mess... be careful out there! ## Frequently Bought Together - Dowsil 791 Sealant Black 310ml (Pack of 2) - Dowsil 785N Silicone Sealant, White 310ml - 791 Silicone Sealant Grey 310ml --- ## 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.hr/products/584993427-dowsil-791-sealant-black-310ml-pack-of-2](https://www.desertcart.hr/products/584993427-dowsil-791-sealant-black-310ml-pack-of-2) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-16*
