Also known as sloshing compounds, these two-part epoxies bond to rough and rusty surfaces in fuel tanks to repair leaks and prevent further corrosion. They withstand permanent immersion in fuel, oil, and harsh solvents. Use them with metal, plastic, and fiberglass tanks. Mix the smaller can with the bigger one and pour into your fuel tank. Rotate the tank to coat the interior and dump out any excess. Allow to cure overnight. Size listed is the combined total of the two parts.

1.5-pint container can treat a 10-gallon fuel tank. 3-pint container can treat a 20-gallon fuel tank.

Use these two-part fillers to rebuild cracked or worn plastic surfaces. The size listed is the combined total of the two parts.

Surface fillers in a cartridge come with a mixer nozzle, but require a gun (sold separately) for dispensing. For best results, use a primer (sold separately).

Surface fillers in a stick have a resin on the outside and a hardener on the inside. Cut the desired amount from the sticks, knead to a uniform color to mix, and press into place. Use with most rigid and semi-rigid types of plastic. They meet NSF/ANSI 61 for use with drinking water.

Even when used under water, these adhesives maintain their strength. The most weather- and chemical-resistant structural adhesives, epoxies tend to work especially well on metals.

The size listed is the combined total of the two parts. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.

WaterWeld and 11801, as well as one-time-use packets, can be applied to wet surfaces or under water.

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Butyl mastic has a clay-like consistency.

Caulk is non-sagging, so it won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement a sealant can sustain. Caulk is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Press this adhesive-backed plastic tape into place for an immediate light-duty seal. It has a score line for easy installation in a corner.

Made from silicone, these sealants are RTV (room-temperature vulcanizing). They’re non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

These sealants include a material certificate with traceable lot number, test report, and product shelf life. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

These sealants include a material certificate with traceable lot number, test report, and product shelf life. Thinner than non-sagging sealants, these sealants flow easily into cracks and have a smooth finish. They’re also known as RTV (room-temperature vulcanizing).

Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Made of silicone, they’re RTV (room-temperature vulcanizing), so they’ll fully harden at room temperature.

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch.

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

Sealants that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

It’s non-sagging, so it won't drip from vertical and overhead surfaces. Made from silicone, this sealant is RTV (room-temperature vulcanizing). It cannot be sold to California because it exceeds local regulatory limits on VOC (volatile organic compounds).

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. This sealant is good for use between dissimilar materials and in environments with wide temperature fluctuation.

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Form seals that resist punctures, cuts, and abrasion to withstand heavy wear and tampering. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
