Review: Worked amazing on my 1963 aluminum boat - I bought this to try and seal a 1963 StarCraft aluminum fishing boat. I noticed water collecting in the boat but was unsure where it was coming from. I decided to buy 2 sets of this but only used 1 with a bit left over. It sealed both side joints, the entire keel, all the bottom rivets, and around the seam on the transom. All I did to prep was power wash the bottom, but the boat had been completely stripped of all paint prior to this sealing. After letting it dry I was very pleased with the durability of the product, and then put 2 coats of bottom paint on the boat. When it went back in the water there were no leaks! I’ve left the boat in the water for several days now and it’s still completely dry! Warning, you cannot send back unused product because it’s flammable. They can ship it but you cannot send it back. Fortunately I was able to sell the unused set I bought to a friend. Overall extremely happy with the finished product on a 59 year old boat.

It is rock-solid/-hard! **Q: How many square ft does one can cover** A: I did the bottom of my drift boat. Best I could figure was about 50 sq.ft.. Two cans did one coat. I put on 2 coats. A little hard to spread it out that thin, but it turned out real nice. I poured it on and used a roller with a thin napped cover, like the ones used for epoxy. **Q: Is this available in Black? I don't see a color listed.** A: It dries a light tan. **Q: Can this expoxy be painted over? What is the actual color when dry? Thanks!** A: YesFrom their website.FAQSWhat is Coat-It and what is it used for? Coat-It is a 100% solids waterproof graphite black epoxy sealer and coating. Its original application is an armor plating type high build coating for the bottom of fishing boats, kayaks and canoes. Cured Coat-It creates slip and lubricity when the boat comes into contact with rocks, gravel or shrubs as well as protects boats from damage. Coat-It can also be used to create a non-skid surface on decks, steps or ramps by spreading medium to fine silica sand over the wet Coat-It. Allow to harden completely and remove excess sand. What surfaces will Coat-It work on? Coat-it bonds very well to aluminum, steel, fiberglass and wood surfaces. What makes Coat-It so tough? Coat-It contains ceramic beads for abrasion resistance, graphite for slip or lubricity and Kevlar® fiber (the same Kevlar® fiber used in bullet proof vests) for extreme toughness. What is the coverage area? Coat-It comes in both 2 lb. and 8 lb. kits. 2 lb. kit: 20 square ft.* 8 lb. kit: 80 square ft.* *depends on porosity of surface and thickness applied. What is the dry time for Coat-It? Mixed Coat-It should be applied within 30 minutes. Adequate dry time is approximately 10-12 hours @ 70°F (21°C) (less than half the time of competitive brands). Cure time decreases with higher temperatures and increases with lower temperatures. Thick coats cure faster than thin coats. Can Coat-It be used in conjunction with fiberglass cloth for additional strength? Yes. Use fiberglass cloth for added strength at plywood joints, etc. When using fiberglass fabrics, use a squeegee for smoothing and spreading resin. When coating large areas, use a foam roller. Using this type of roller assures a smooth uniform finish when applied according to directions. Can Coat-It be painted? Yes. For maximum ultraviolet protection, allow Coat-It to cure thoroughly, sand lightly and apply a good grade of marine paint or Famowood Dura-Tuff (above water surfaces only). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked amazing on my 1963 aluminum boat *by A***R on August 31, 2022* I bought this to try and seal a 1963 StarCraft aluminum fishing boat.

I'm happy with the results I achieved. I will definitely consider using this product again. A couple of caveats and notes about usage: The biggest problem I had was evenly coating the walls of the box. The epoxy on the walls flowed downward with gravity. As a result, the floor ended up with extra material, and the thickness of the coating is markedly reduced at higher positions along each wall. Enough coating remains even at the top of the walls to preclude the need for a second coat. But a different strategy is required to do a really nice job. Perhaps it is doing each wall separately, or perhaps it is applying multiple very thin coats. I'm not sure, but before I try coating vertical surfaces again I'll want to do some more reading, or experimentation. Based on my experiences, I believe the working and cure times for this epoxy are conservative, that is perhaps actual times are longer than published times. The second issue I had was with bubbling. I experienced some bubbles breaking the surface of the coating on the walls of the battery box, leaving some pock marks in the coating. These imperfections aren't terribly obvious, and for my needs they don't matter. If I wanted a quality finish, I would have been disappointed, done some sanding, and tried a second coat. By comparison, however, the floor turned out great -- no bubbles there, only some variation in thickness due to the aforementioned flows from the walls. I'm not sure if the bubbles were caused by the method of application, or the mixing. Because the floor of the box turned out so nicely, I tend to think its probably the former. Adhesion to plywood is excellent, and I didn't really do much to prepare the surface beyond wiping it down with a damp cloth beforehand to remove any loose particulates. I had drilled a couple of 7/8" holes in the back wall of the box for venting prior to coating. The coating pooled at the bottom of the holes (the plywood is 3/4" thick), so they were no longer round. I used a hole saw after cure to fix that problem. The bond between wood and epoxy is excellent -- the epoxy did not chip or split away from the wood as I drilled it. One last point: the estimated coverage seems right on if not slightly better than published. ## Frequently Bought Together - Amazing GOOP 5400040 Coat-It Waterproof Epoxy Sealer & Protector - 2 lb Kit, Dark Gray - TotalBoat Aluminum Boat Paint for Canoes, Bass Boats, Dinghies, Duck Boats, Jon Boats and Pontoons (Light Gray), 1 Quarts (Pack of 1) - Amazing GOOP 5400060 Coat-It Epoxy Sealer Adhesive Kit - 8 lb --- ## 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/7742224-amazing-goop-5400040-coat-it-waterproof-epoxy-sealer-and-protector](https://www.desertcart.us/products/7742224-amazing-goop-5400040-coat-it-waterproof-epoxy-sealer-and-protector) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-10*
