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.

Rated 2 out of 5 by from No Instructions on how to mix etc ! There are No Instructions on how to mix, apply, or work time with this product. Mush wasted time trying to figure something out. Very thick material hard to work into small spaces. Como On 3M put some directions on the can or get it

Rated 4 out of 5 by from Needs mixing instructions No mixing instructions like with the 3M resin which states 5 drops of hardener per oz. of resin. So it is kind of a guess how much hardener should be used for 1oz of jelly. 1 oz. tube hardener for whole 16 oz. can of jelly. It should say something like squeeze out 1/2 inch of hardener for every ounce of jelly. A little sense goes a long way, r.e. the previous review about not being able to work into cloth. The jelly is much too thick. Use resin for the cloth. For large holes jelly would be used after a hole is patched with cloth/mat. Instructions state: "Fills SMALL holes and can be used with backing strips, fiberglass mat or cloth". This could be clearer and should say used over cloth or mat, not to apply cloth/mat or work into. Use like one would spread regular bondo and then sand.

Rated 3 out of 5 by from Not thrilled I bought the Resin Jelly instead of regular resin based on the very limited description on the label. The product probably has its merits but there are absolutely no application or mixing instructions on the product package or 3M website. It is nearly impossible to work the Jelly into fibreglass cloth especially if you have a large hole to cover or work overhead. It takes a stiff putty knife and a lot of pressure to force the resin into cloth. Forget about applying on the work surface, the resin needs to be worked in to the cloth on a flat, horizontal surface then the cloth applied to the work. Make sure you have some plastic putty knives to work with, the product is too sticky to use with paint brushes.
