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.

To use, you must measure out an approximate amount of hardener from a "toothpaste" tube, and thoroughly mix the hardener into the resin. This is not completely trivial, since the resin is highly viscous because of the fiberglass filler. By the time the hardener and resin are properly mixed, you have, at summer temperatures, only 2-3 minutes to apply the resin to your project. Thus, you mix only a little at a time.
The fiberglass filler makes the resin quite strong. I had pressure-washed my composter before applying the resin to the outside. The pressure washing (from the inside) removed the thinnest of the rusted metal, showing where the weakest areas were. I applied the resin to these areas (about 5 square feet, keeping it about 1/4" thick, spreading with a small spatula-like board (about 1" wide). The metal door to the composter had a serious crack, so I used some fiberglass cloth under the resin. I was concerned that the door, which must flex slightly, would be too stiff, but it flexes sufficiently and works perfectly.
There were a few places where I might have had slightly less hardener than preferred. These were slightly sticky for a day -- not enough to coat your hand or glove, but enough to notice that it wasn't perfectly hard. After a day, it hardened perfectly. This is a symptom, I believe, of insufficient hardener. (I didn't measure -- just estimated.)
I have since filled the composter with considerable heavy bulk, and the resin is holding perfectly (about 2 months). It bonded primarily to oxidized paint, and is a firm bond. It's a composter, so I didn't sand and finish the resin. Maybe someday if I'm ever bored...
Bottom line, the resin is strong, and hardens well. The color is ugly, but it's meant to be painted. I will use this again if I have repairs to make to sheet metal.
One down side of this stuff is that the white platic lid is way to tight and i had to break it in order to remove it.
