UPDATE: failed after about 5 weeks. i was convinced i had a permanent repair after 3 weeks, but my repair started to drip. my gas tank is plastic (2008 scion xb) and the repair is on the bottom. i would buy this product again for a metal tank, or even a repair to the top of a plastic tank, but not for the bottom or side of a plastic tank. bummer. i still give it 5 stars, as the company website warns it does not work on some plastic and i am sure it works well for metal tanks. Review: Great product - Works better than expected! Highly recommend. Great product. Im buying it again. ## Features - Hand-mixable, steel-reinforced, non-rusting epoxy putty that quickly repairs or rebuilds anything made of metal - Great for gas tanks, radiators, lawn and garden equipment, water tanks and all metals - Sets in 5 minutes and fully cures dark grey in 1 hour with a tensile strength of 900 PSI - Once cured, it can be drilled, tapped, machined, ground, filed and painted and will withstand temperatures up to 300ºF - J-B Weld is proudly made in the USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00R2CDUWE | | Brand | J-B Weld | | Brand Name | J-B Weld | | Color | Dark Grey | | Compatible Material | Metal | | Container Type | Can | | Customer Reviews | 4.5 out of 5 stars 2,355 Reviews | | Full Cure Time | 60 minutes | | Global Trade Identification Number | 00043425082176 | | Included Components | J-B Weld 8217 TankWeld Gas Tank Repair - 1 oz. | | Item Form | Putty | | Item Package Quantity | 1 | | Item Type Name | J-B Weld 8217 TankWeld Gas Tank Repair - 1 oz. | | Item Weight | 45 g | | Manufacturer | JBWeld | | Material | Plastic | | Material Type | Plastic | | Model | 8217 | | Number of Pieces | 1 | | Other Special Features of the Product | Steel reinforced, Chemical resistant, NSF certified, Potable water safe | | Part Number | 8217 | | Special Feature | Steel reinforced, Chemical resistant, NSF certified, Potable water safe | | Specific Uses For Product | Fuel tanks, Metal radiators, Metal fuel or chemical tanks, Metal housings, Stripped threads, Wall Repair Specific Uses For Product Fuel tanks, Metal radiators, Metal fuel or chemical tanks, Metal housings, Stripped threads, Wall Repair See more | | Tensile Strength | 900 psi | | UPC | 043425082176 | | Unit Count | 1 Ounce | | Viscosity Level | High | | Volume | 1 fluid ounces | | Warranty Description | as listed | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** J-B Weld - **Item Form:** Putty - **Material:** Plastic - **Special Feature:** Steel reinforced, Chemical resistant, NSF certified, Potable water safe ## Images ![8217 TankWeld Gas Tank Repair - 1 oz.,Dark Grey - Image 1](https://m.media-amazon.com/images/I/71j-YT63RyL.jpg) ## Questions & Answers **Q: Will it bind to plastic? The top of my fuel pump housing has a small chip, and its now leaking fumes. How well will this patch up the plastic housing?** A: I used this to seal a hole chewed (by a squirrel) in the top of my Craftsman snowblower fuel tank. It bonded to the plastic tank and sealed it completely. **Q: Can i use this on a pressured gas line?** A: I would not recommend this due to safety reasons. Best to change the line with an approved replacement. **Q: Does the gas tank have to be completely empty and dry? I have a tiny hole in the bottom of a metal gas tank.** A: For best results you want to make sure the gas tank is totally empty and totally dry so that the epoxy can adhere to the metal if it's wet it won't adhere to it well at all **Q: Will a magnet stick to the cured epoxy?** A: Was very easy to attach in place but nemember to scratch surface to bare metal, then it stck very well, stay in place and seal the hole. Very easy to use, I like it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ saved me a pile of money *by S***S on June 23, 2017* i came to my car (scion xb) one day and there was a huge puddle of gas under it. something must've come up from the road and put a small, pencil-sized hole in the tank (tank is plastic, with fiber mesh reinforcement). had enough fumes to make it to the nearby toyota service center and was told my only solution was a new, $1200 fuel tank. so i had AAA tow it to my house, and had amazon deliver a tube of JB Weld same day for less than $15. next day i was up and running again. it's been a few weeks now and i believe the repair is permanent -- no moisture or indication that the repair won't last. it's as easy to use as you'd hope and seems to work equally well. saved more than $1185, so i couldn't be happier. 2 thumbs way up.
