Metal Glue,Muffler Repair kit，Waterproof Sealing Epoxy

PLJOFRSHI Metal Glue is a two-part, waterproof epoxy repair kit designed to bond, fill and seal metal, plastic, ceramic and fiberglass with high-temperature and impact resistance.

This repair kit includes two 1.76 oz cartridges pre-measured in a 1:1 ratio plus a pusher and scraper, giving you a ready-to-mix cold-welding adhesive for automotive, marine and household fixes. The formula cures at room temperature into a rigid, high-hardness filler that resists heat, wear and mild corrosion, letting you fix mufflers, radiators, tanks, bumpers and more without a torch or welding rig.

How does PLJOFRSHI Metal Glue handle hot automotive parts?

The cured epoxy offers thermal toughness suitable for many warm engine-bay and exhaust-area repairs. While not a replacement for full welding on extreme high-heat zones, it withstands elevated temperatures and maintains structural strength under repeated thermal cycles.

• High-temperature resistant epoxy formulation, suitable for mufflers and exhaust patching
• Strong adhesion to steel and iron after full cure
• Good impact and wear resistance for road vibrations

How do I prepare and apply the two-part epoxy correctly?

Dispense equal amounts of resin and hardener onto a clean, flat surface, then stir thoroughly for about five minutes until uniform in color. Apply the mixed paste to a clean, dry surface and position parts as needed; allow horizontal curing for best results and wait a full 24 hours before handling.

• Push equal volumes from both syringes (1:1 mix) using the included pusher
• Mix vigorously for 5 minutes to avoid weak spots in the bond
• Leave to cure 24 hours; fully harden before pressurized or load-bearing use

What materials will this epoxy bond and repair?

PLJOFRSHI Metal Glue bonds a wide range of substrates — metals, plastics, ceramics, fiberglass and painted surfaces. It fills cracks, seals holes and reinforces thin or fractured parts, making it a versatile multi-material repair adhesive for home, shop and marine use.

• Effective on steel, aluminum, cast metal and iron
• Works on common plastics, ceramic pieces, fiberglass panels and painted surfaces
• Seals leaks in tanks, pipes, mufflers and radiators when properly prepared

How durable and safe is the cured joint?

Once fully cured, the epoxy creates a hard, wear-resistant bond with good corrosion and impact resistance. The product is presented as a low-odor, nonirritating cold-welding adhesive, but standard safety practices—gloves and ventilation—are recommended during mixing and application.

• High hardness and mechanical strength after full cure
• Resistant to impacts, abrasion and many environmental exposures
• Non-irritating odor profile, but follow SDS guidance for safe handling

Who is this for: PLJOFRSHI Metal Glue is aimed at DIYers, mechanics, boat owners and maintenance professionals who need a portable, heavy-duty repair adhesive for metal, plastic and composite parts. It suits quick field repairs, emergency fixes and projects where welding is impractical—especially for mufflers, radiators, tanks, bumpers, fiberglass panels and household fixtures. If you want a robust, room-temperature-curing epoxy kit with clear mix instructions and tools included, this product provides a convenient alternative to heat-based repairs.
