Review: Need to work fast but product works well and cures to a smooth and hard surface - This product works as advertised. I have a basketball hoop and the plastic base got cracked. This was able to seal the crack well and the basin is holding water well. We'll see how it stands up over time but the epoxy dried hard and smooth so it looks promising. As noted by others... you need to work fast when using this! My first attempt at using this product didn't work out well as I took too long, and before I had finished painstakingly applying the epoxy mix it grew extremely hot and started to harden before I'd applied much of it. My second attempt I was ready and worked quickly. One thing worth noting is that the epoxy comes out quite runny so if you're applying to a curved surface be aware of that, and you might want to just cut a corner of the epoxy packet so that you are applying a narrow-ish stream with more control than what I initially did. There is more material in here than I initially anticipated. Review: Sticks like glue. - Excellent product! Fixed my Angel Fish's tank. Very easy to use. Also figured out how to multi-task this product when a patch on my Uniform got loose on one end. I did not have access to a sewing machine, and this actually fixed my patch from hangin off! It even held going through the washing machine. ## Features - State-of-the-art components - Easy-to-follow instructions with photographs - Designed to harden within 8-10 minutes and cures in 30 minutes - Permanent repair - Suggested Applications: windshield washer reservoirs, radiator overflow tanks, coolant reservoirs, water tanks, waste tanks *Not for use on plastic fuel tanks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007TQWM4 | | Best Sellers Rank | #36,693 in Automotive ( See Top 100 in Automotive ) #12 in Powersports Gas Tanks | | Brand Name | Permatex | | Color | No Color | | Compatible Material | Fiberglass, Plastic | | Container Type | Tube, Bottle | | Customer Reviews | 4.1 4.1 out of 5 stars (474) | | Full Cure Time | 30 Minutes | | Included Components | Other Vehicle Parts( AUTO_PART ),Performance Parts - Underhood, Fuel System, automotive-fuel-tanks | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Type Name | Plastic Tank Repair Kt 6/Cs | | Item Weight | 0.2 Pounds | | Manufacturer | Permatex | | Material Type | Plastic | | Model | 09100 | | Other Special Features of the Product | Quick Curing Time, Easy to Use | | Part Number | PX09100 | | Specific Uses For Product | Fleet and plant maintenance. | | UPC | 077349611556 | | Unit Count | 1.0 Count | | Viscosity Level | Medium to High | | Warranty Description | WARRANTY | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Permatex - **Item Form:** Liquid - **Material:** Plastic - **Special Feature:** Quick Curing Time, Easy to Use - **Specific Uses For Product:** Fleet and plant maintenance. ## Images ![Plastic Tank Repair Kit - Image 1](https://m.media-amazon.com/images/I/91hazG0JdVL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will yhis work on the bottom of a black water tank?** A: We used it to repair a separated seam on the drinking water tank for our camper. I don’t see why it wouldn’t work for your application. It’s held for a solid year, with several uses. **Q: My coolant tank isn't cracked but has that white spiderweb look on the top near the cap, would this cover that section, to prevent it from cracking?** A: I think so. My tank had a small hole and it was very brittle in the area with cracks and it has done just fine for several months now. Much cheaper than paying $100 bucks for OEM tank. **Q: Will this work on rubber?** A: Does it say it works on rubber? If it does then yes otherwise buyer beware. Please read shut the product uses and descriptions before asking this type of question. **Q: Which is the best sealent for stopping leakage in sintex water tank** A: I ended up using gorilla glue, it was easy to apply and leaves a clear watertight seal. Remove the tank, drain it, wash it well with soap and water, dry it well, apply gorilla glue to the cracks and let dry, then water test before you reinstall the tank. Easy, clean and works great, has lasted over two years since I repaired. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Need to work fast but product works well and cures to a smooth and hard surface *by L***. on June 25, 2016* This product works as advertised. I have a basketball hoop and the plastic base got cracked. This was able to seal the crack well and the basin is holding water well. We'll see how it stands up over time but the epoxy dried hard and smooth so it looks promising. As noted by others... you need to work fast when using this! My first attempt at using this product didn't work out well as I took too long, and before I had finished painstakingly applying the epoxy mix it grew extremely hot and started to harden before I'd applied much of it.

Also figured out how to multi-task this product when a patch on my Uniform got loose on one end. I did not have access to a sewing machine, and this actually fixed my patch from hangin off! It even held going through the washing machine. ### ⭐⭐⭐⭐ Repaired things well, but this can get HOT *by P***N on March 28, 2025* This seemed to work well, and repaired the 140 gallon tank rock solid, but be advised when they say that after mixing the epoxy - that it can get hot. They don't mean hot, they mean HOT and it WILL burn your fingers if you aren't careful. The chemical reaction works fast, so plan on spreading it all out within 60-90 seconds. After that, the bag of the remaining mix will be too hot to even touch, so put it on a paper plate that you can just toss afterwards. I also feel they could give you more epoxy because I felt I was about 10% low. But overall the repair went well, and no leaks at this point in the tank. Highly recommended. ## Frequently Bought Together - Permatex® Plastic Tank Repair Kit - J-B Weld 8237 PlasticWeld Plastic Repair Epoxy Putty - 2 oz. - J-B Weld 8277 WaterWeld Epoxy Putty Stick - 2 oz., Off White --- ## 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/4523503-plastic-tank-repair-kit](https://www.desertcart.jp/products/4523503-plastic-tank-repair-kit) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-07*
