In other words, use black sealant only on black material, white only on white. **Q: Want to use under a white epdm roof to adhere to new plywood - any problem using this black adhesive? thank you.** A: Worked fine for me. Roof was peeling back from wind and this held as a repair; press down epdm after application while it cures. Then covered edge with self leveling white lap sealant. **Q: what is the difference with this and the 2300?** A: The 2300 i have used is more runny and sticks to everything to include bronze and stainless. **Q: Can this product be applied to pond liner to glue onto another piece of liner? Would it be harmful to fish?** A: That's exactly what I did, nothing changed with the comets or Shubunkins. ## Frequently Bought Together - GEOCEL GC55103 4500 Roof Bonding Sealant, 10 Ounce Cartridge, Black - Oatey Oatey-14137 14137 Rain Collar 3"-4" No-Calk Roof Flashing, 1 Count (Pack of 1), Black - Oatey 14136 Rain Collar 1.5"-3" No-Calk Roof Flashing, 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.jp/products/42016620-4500-roof-bonding-sealant-10-fl-oz-black](https://www.desertcart.jp/products/42016620-4500-roof-bonding-sealant-10-fl-oz-black) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-16*
