None of us want to be in a situation where one of our motorcycle’s painted components is damaged. Replacing a fuel tank or fender can be very expensive. However, if a damaged piece is salvageable, consider repairing it yourself. You will save a lot of money if you bring a component to your painter, already repaired and prepped.

In this video, Bob gives us an overview on metal fillers or body fillers. There are three types of body fillers:

Duraglass – fiberglass type fillers. It’s the hardest to work out of the three, but it is water resistant and creates a strong environmental barrier.

Bondos – workable metal fillers.

Putties – for finnish work. Thin, final layers.

The key to success when working with metal fillers is to reform and correct the metal component until you will only need to fill an 1/8″ or less with filler. Correctly mixing/introducing the hardener is very important. Too much hardener, and the filler will harden before you can evenly spread it over the component. Too little and the filler may, actually never fully harden. When mixing, never stir. Stirring introduces a lot of air. Simply fold the filler over the hardener and work out over your board. Knead out the filler with a good, clean spreader. Most fillers will change color after the hardener is introduced. Work the filler in different directions and always stop to remove any contaminants found in your work.

Every repair is different. There can be a multitude of ways to correctly accomplish the same repair. If you have never tried this type of work before, try practicing or experimenting on an old fender or fuel tank. Then move on and repair the damage on your fender that has been driving you crazy.
