AP Products Versachem Plastic Tank & Radiator Repair Kit — 30 g epoxy, fast 20-min cure, fuel-resistant

The AP Products Versachem 90214 Plastic Tank and Radiator Repair Kit is a two-part epoxy patch that permanently seals fuel tank and radiator leaks up to 1/2" in under 20 minutes.

This compact 30-gram kit contains pre-measured resin and hardener designed to bond to plastic and metal surfaces without removing the tank. It creates a solvent-resistant, heat-tolerant repair that resists gasoline, diesel and kerosene and cures with a tensile strength suitable for automotive and small-engine applications. The fast cure time and room-temperature working range make it a practical emergency fix or a reliable permanent repair when welding or part replacement isn’t feasible.

How quickly will this kit stop a fuel leak?

The Versachem 90214 formula begins curing immediately after mixing and provides a functional repair in less than 20 minutes under typical conditions. Full strength develops as the epoxy continues to set and harden over time, producing a durable bond suitable for pressurized and submerged areas when used correctly.

• Functional seal time: under 20 minutes for most small leaks
• Final strength: develops after initial cure — tensile strength ~1500 PSI
• Works on pinholes, hairline cracks, rust-outs and holes up to 1/2"

Can I use this on plastic and metal fuel tanks without removing them?

Yes — the product is formulated to adhere to both plastic and metal surfaces so tank removal is not usually required. For best adhesion, clean and dry the repair area thoroughly and roughen smooth surfaces before applying the epoxy to improve mechanical bonding.

• Recommended prep: clean, degrease and abrade the repair area
• No tank removal necessary for many repairs; access to the leak area still required
• Resistant to gasoline, diesel and kerosene after full cure

What size leaks can this kit repair and how durable is the fix?

The kit is intended for holes and damage up to 1/2" (12 mm) in diameter and excels on small, localized failures like pinholes and hairline cracks. Once cured it tolerates temperatures from 40°F to 200°F and offers a strong, chemical-resistant bond suitable for fuel systems and oil pans in normal operating conditions.

• Maximum recommended hole size: 1/2" diameter
• Operating temperature range: 40°F to 200°F (4°C to 93°C)
• Tensile strength: approximately 1500 PSI for reliable mechanical resistance

How do I prepare and apply the repair for the best result?

Have the repair area ready before mixing the resin and hardener, since the working time is limited. Mix thoroughly, apply the epoxy to the prepared surface, and allow it to cure — heat is generated during cure, so avoid sealed containers and follow safety precautions on the pouch.

• Surface prep: remove fuel, dirt, rust, oil; sand or file smooth areas
• Mix: combine resin and hardener thoroughly, then apply immediately
• Curing: allow initial set in minutes; full cure follows — expect heat generation during cure

Who is this for? The AP Products Versachem 90214 kit is aimed at mechanics, DIY vehicle owners, small-fleet operators and anyone needing a quick, durable repair to fuel tanks, radiators or oil pans when welding or part replacement is impractical. It’s particularly useful for emergency roadside fixes, workshop patch jobs, and situations where chemical resistance to fuels is required. If you need a compact, fast-curing epoxy repair that bonds to plastic and metal and handles common automotive fluids, this kit is engineered to meet that need.

• Permanently repairs gasoline and diesel fuel tank leaks
• Repairs leaks in less than 20 minutes; no draining or welding required
• Chemical solvent resistance to gasoline, diesel and kerosene
• Temperature Range: 40°F to 200°F
• Suggested Applications: Repair pinholes, rust-outs, hairline cracks and holes up to 1/2" in diameter
