Tear Mender RapidFix UV Fiber Repair Patch 6" x 6" — Self-Adhesive Fiberglass, Fast-Curing & Sandable

Tear Mender RapidFix UV Fiber Repair Patch (6" x 6") is a self-adhesive, fiberglass-reinforced polyester patch that cures with UV light or sunlight to create a durable, sandable and paintable permanent repair.

Keep a ready patch for fast fixes on vehicles, boats, RVs, plumbing and building surfaces — no messy mixing, no heat source and minimal tools required. The 6" x 6" RapidFix patch adheres to most rigid and semi-rigid substrates (except polypropylene), cures in minutes under bright UV and forms a tough, chemical-resistant bond that can be drilled, sanded and painted within an hour.

How quickly does this patch set and when can I finish the repair?

The patch sets rapidly when exposed to a UV lamp or direct sunlight: typically 5–10 minutes with a dedicated UV lamp and about 50 minutes on a cloudy day. After the patch cures to a solid state you can machine it like conventional composites.

• Cures in 5–10 minutes under UV lamp
• About 50 minutes in diffuse/cloudy sunlight
• Drill, sand and paint in under an hour after curing
• No heat or mixing required

What surfaces and repairs are best for the RapidFix UV Fiber Patch?

The fiberglass-reinforced polyester fabric bonds to most surfaces except polypropylene (PP) and is ideal for automotive bodywork, marine gelcoat, metal ducts and many plumbing or roofing applications. It’s designed for both exterior and interior fixes where a stiff, long-lasting patch is required.

• Bumpers, headlamp housings and exterior automotive trim
• RV, trailer and boat hull repairs including fiberglass panels
• Pipes, gutters, ducts, tanks and drainage repairs
• Roof flashing, metal siding, switch boxes and utility covers

How durable and chemical-resistant is the repair?

The material is a fiberglass-reinforced polyester that becomes rigid and durable after curing, offering resistance to many common chemicals, solvents and oils. It is non-flammable and non-toxic when used as directed, making it a practical choice for demanding outdoor and mechanical environments.

• Fiberglass reinforcement adds tensile strength and rigidity
• Resists oils, solvents and many common chemicals
• Non-flammable, non-toxic adhesive formulation
• Made in the USA for consistent quality

How easy is it to apply — what tools or prep are needed?

Application is straightforward: clean and dry the repair area, cut the patch to shape if needed, press in place and expose to UV light or sunlight. Minimal tools are required, and the cured patch accepts sanding and painting to blend with the surrounding surface.

• Surface must be clean, dry and free of loose debris or oils
• Cut to shape with scissors or utility knife before application
• Apply firm pressure to seat the adhesive layer
• Use a UV lamp for fastest cure; sunlight works outdoors
