They started cracking around the edges about a year ago and were getting very brittle and started leaking water inside. Although I didn’t, you could’ve put your finger right through the skylights, they were so thin and weathered. The camper isn’t worth much anymore, so I wasn’t going to spend the money for new skylights. I wanted a quality clear sealant to brush on over the skylights, so it still let light in. This clear Flexseal fit the bill. After brushing 2 coats on them, they are as strong as they were when they were new. It stiffened them up tremendously and I’ve have no more leaks. I’m good for the rest of the camping season. Review: Amazing Flex Seal for Old Wood Boat Seats - Flex Seal is amazing and easy to apply. I needed to waterproof my fishing boat wooden seats that were the old school of paint on them and they needed some tinder loving care to get them back to a good state. I sanded the wood seats to get a good surface first, then applied the Flex Seal. OMG after a first coat I was amazed how well it adhered to the old plywood seats! Heads up though, do the prep work first, then apply the Flex seal with a good brush with even strokes in one direction. Allow it to be done in warm clear weather as it will take awhile to fully cure. I let it dry for a full week. Amazing finish in the final result. It is waterproof now too! Love it. I used the light gray. ## Features - Flex Seal Liquid is liquid rubber in a can! Now you can brush, roll, dip or pour it on! - Use anywhere you need a watertight, flexible rubberized coating - Goes on smooth and covers fast, sealing out water, air and moisture - UV Resistant - Prevents rust and corrosion.

I'd like to paint a temporary white layer on my jeep hard top. But want to remove it after summer.** A: Flex Seal Liquid can be removed with mineral spirits, acetone, or a citrus based cleaner, but it may be difficult to remove from the entire roof of your car. We recommend testing in a small area so you can see how easy you'll be able to remove it. **Q: I would like to seal my rv septic tank with flex seal. will this hold up against the chemicals as well? and is it able to hold together with weight?** A: If I were you I would use the Flex Seal Tape, and follow that with the liquid or spray to seal the edges around the tape. If it's under high pressure, does not seal well. Good luck! **Q: How many square feet does a gallon cover,and has any one used on there Motor home/RV trailer?** A: Many people have had great success using Flex Seal on their motor homes. Here is your coverage ranges Flex Seal Liquid. 1 Large 16oz - up to 20Sq. Ft., 1 Jumbo 32oz - up to 40Sq. Ft., 1 Gallon can - up to 150Sq. Ft. **Q: can you use this to paint plastic? Flower pots specifically, or will it not stick / weird finish?** A: WE have not tested Flex Tape for this application, however Flex Tape will have excellent adhesion on many surfaces including PVC, acrylic, metal, steel, copper, aluminum, wood, ceramic, porcelain, tile, glass, rubber, fiberglass, stucco, plaster, stone, cement, concrete, dry wall, EPDM roofs, some plastics, fabrics, vinyls and so much more! Some materials may take up to 24 hours to reach maximum hold . Always test before use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Crazy good stuff *by T***J on September 8, 2026* I have a 20 year old 5th wheel camper that has 2 clear plastic skylights.

I needed to waterproof my fishing boat wooden seats that were the old school of paint on them and they needed some tinder loving care to get them back to a good state. I sanded the wood seats to get a good surface first, then applied the Flex Seal. OMG after a first coat I was amazed how well it adhered to the old plywood seats!

I used the light gray. ### ⭐⭐⭐⭐ A little expensive, but it does the job. *by G***R on April 6, 2026* I used this on a steel trash can that I store bird seed in. The top had a gash in it and no matter what I did, water would get in and ruin the seed. I hated to throw it away since that was the only problem. A can of this, and the problem was solved. It's a little spendy for the amount you get which is why I removed 1 star. But there's no question it works good. My only other gripe is that it takes a long time to set up and dry. So if you can keep your project level and dry for 24 hours, that will go a long way to helping it cure. I just used a disposable paint brush to apply it and I kept the now hard brush for future applications. It's fairly durable depending on what you're trying to accomplish. I tried using it on the feet of my deck chairs hoping it would save wear and tear on my deck? Not a good idea, it just fell off after a couple of uses. But for sealing, this is a good product. ## Frequently Bought Together - Flex Seal Liquid, 16 oz, White, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - Flex Seal Liquid, 16 oz, Clear, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry --- ## 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.no/products/33726257-rubber-sealant-coating-waterproof-white-16-oz](https://www.desertcart.no/products/33726257-rubber-sealant-coating-waterproof-white-16-oz) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-11*
