PlasticWeld™ is a hand-mixable, fast-setting epoxy putty that forms a durable bond to most major plastic types. *After mixing, it forms a polymer compound that can be molded or used to build up and repair just about anything made from plastic. When cured, it can be sawed, drilled, carved, sanded and painted. PlasticWeld™ has a 20-25 minute work life; functional cure occurs in 2-3 hours. PlasticWeld™ cures to an off-white color, is rated at a tensile strength of 600 PSI. Does not adhere to polyethylene, polypropylene or some other plastics. Test for adhesion first.

Will JB Weld fix a gas tank?

Just so, does Flex Seal work on gas tanks? here

Also Know, how long will JB Weld last? At room temperature, J-B Weld sets in 4-6 hours to a dark grey color. A full cure is reached in 15-24 hours. J-B Weld has a tensile strength of 3960 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured.

A: No, Flex Seal is not made to withstand extreme heat or pressure. Q: Can I use it on a gasoline tank? A: No, Flex Seal should not be used to seal a gasoline tank, oil tank or any other flammable material.

What you need for a wet repair is JB Weld Autoweld or SteelStik epoxy putty stick. Once cured, the epoxy can withstand 300-degrees and 900 psi of pressure, so it will be perfect for your leaky gas tank. This is the fastest way to keep that expensive fuel in the tank and not on the asphalt. [links]

BTW, there should be some markings molded into the tank for recycling purposes that tell you what the material the tank is made from.

Another option if it a seam that is leaking is to clean the plastic completely with non-chlorinated brake cleaner or similar and then use a wicking viscosity of super glue. Super glue is highly resistant to both gasoline and ethanol. here

MarineWeld™ is a specially formulated two-part epoxy cold weld system that provides for strong, lasting repairs for bonding different or similar surfaces, such as aluminum, metal, composites, fiberglass and others. MarineWeld™ sets in 4-6 hours at room temperature and is fully cured to a dark grey color in 15-24 hours. Once cured, it can be shaped, tapped, filed, sanded and drilled and will retain its strength above or below the waters' surface. MarineWeld™ has a 1:1 mixing ratio and tensile strength of 5020 PSI.
