It's white. **Q: Rain barrel leaking thru small cracks in plastic ring/surface surrounding where faucet screws in. will this fix leak? or loctite epoxy better? thanks!** A: Used this on a koi pond skimmer extension I made from lexan which has remained leak free for 3 years with water running over it from a pool pump . So two different forms of plastic glued without leaks. This is some sticky sealant so I would say it would do the job. Sand the cracks just to roughup the surface with some 360 grit sandpaper and this sealant should fix your problem , it's flexable after it cures so movement won't break the seal . I also used this to glue a John deere riding mower seat back on the seat frame and it is still holding. Locite makes quality thread lockers and sealants and I have never had a bad day with their products. **Q: Will it work to hold a corner bumper to a metal dock?** A: Not by itself. You will need some fastener as well. This stuff does not bond well to some plastics such as HDPE or polypropylene. **Q: Will this work with EPS/XPS Foamboard? looking to seal DIY camper shell to trailer bed. Shell is 2" Pink foamboard sandwich covered with 1/8" plywood.** A: aIt will work but there are better alternatives out there it is more of a sealant it has good adhesion but takes 24 hours to reach full strength ## Frequently Bought Together - Loctite PL Marine Fast Cure Adhesive Sealants, Waterproof Construction Glue for Fiberglass, Vinyl, Glass & More - 3 fl oz Cartridge, Pack of 1 - Dicor BT-1834-1 Butyl Seal Tape - 1/8" x 3/4" x 30' Repair Tape for RV, Trailer, Motorhome, Window, and Vent Sealing - Dicor 501LSW-1 HAPS-Free Self-Leveling Lap Sealant for horizontal surfaces - 10.3 Oz, White, Secure, Ideal for RV Roofing, Maintenance, Repair, Appliance Application --- ## 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/713324995-pl-marine-fast-cure-adhesive-sealants-waterproof-construction-glue-fiberglass](https://www.desertcart.us/products/713324995-pl-marine-fast-cure-adhesive-sealants-waterproof-construction-glue-fiberglass) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-25*
