Bondo® Fiberglass Resin Jelly features a resin that is reinforced with milled fiberglass for a thicker consistency. More firm but still workable, it provides smooth, drip-free application. It can be used in small holes and minor rust-outs without backing strips, cloths and mats. This waterproof fiberglass resin jelly is especially suitable for vertical surfaces on autos and boats.

A Firm Fiberglass Resin that's Easy to Work With
Bondo® Fiberglass Resin Jelly features tiny milled glass fibers that add strength and provide a thicker consistency for filling holes and rust-outs in auto body repair. This formula is ideal for vertical work such as car doors or boat hulls where standard resin can drip down the surface and cause extra work and cleanup. Also, there's no need for fiberglass mats, cloths and backing strips with small holes which cuts down on work time. For repairing larger holes where even more strength is needed, these added materials can be easily used.

Easy from Mixing to Sanding
This fiberglass resin jelly filler is easily mixed using the included Bondo® Red Cream Hardener, designed specifically for use with Bondo® fillers. It also features a fast-drying formula that is sandable in as little as 20 minutes.

For Auto or Marine
This waterproof filler is ideal for repairing and filling minor rusted-out holes in metal, wood and automotive fiberglass. It is compatible with most paint systems for cars and boats.

Use During the Fill Stage of the 3M™ Body Repair System
Even a small repair can seem complex at first. So 3M's Body Repair System simplifies the entire automotive body repair process by dividing it into four stages:

  • Stage 1 — Prepare. This stage includes pulling dents, removal of paint and rust and efficient, effective masking of the area.
  • Stage 2 — Fill. This stage involves patching holes with reinforced filler and smoothing and shaping filler before painting.
  • Stage 3 — Paint. This stage includes painting the area and blending and smoothing primer and paint.
  • Stage 4 — Finish. The final stage for showroom-grade results: removing small defects, sealing and polishing clear coats and other painted surfaces.

3M supplies premium products such as abrasives, tapes, body fillers and tools for every stage. This system helps you work easily, efficiently and successfully across the entire body repair process.

Bringing Science to the Art of Auto Body Repair
As a brand of 3M, Bondo® is well known among collision repair professionals and others who are committed to helping you restore the beauty and value to your cars and boats. This milled fiberglass reinforced resin jelly is another way that 3M applies science to life — and helps you rediscover the excitement of the vehicles you own.
