Want to buy this? You will get a tube of the hardener which when mixed with the filler forms a nice creamy consistency to apply on the affected area. The mixture creates a chemical reaction to cure the dents, scratches or rust etc.

Best Car Body Fillers Buying Guide
A good body filler can make repairing your vehicle faster and a lot easier. But, with the many options in the market choosing the right one can be a little hectic.
And while our reviews above will provide some good recommendations, you still need to consider the following important points when shopping.
#1. Types of Car Body Filler
Metal: Metal fillers consist of aluminium metal parts and they are some of the most used fillers. They are known for their low moisture retention and do not shrink once applied which means you will not need to worry about reshaping.
Although they also provide a smoother finish when compared to other filer types, they are also more expensive.
Fiberglass: Fiberglass or resin fillers as they are also known as consist of metal and fiberglass particles.
This type of filler is applied by first sanding the dent and then applying the filler in layers. Heat is then applied to ensure proper curing before sanding.
Lightweight: Lightweight fillers are easy to sand and water resistant. They are often used as a final layer when repairing dents because they are often not thick enough to cover large holes. But they contain high amounts of resin to ensure the repairs last long enough.
Before you buy any car body filler, don’t forget checking if it is compatible to your damaged surface, auto body or anything you want to repair.
Fillers are made for different surfaces such as wood, concrete, metal, or plastic, and so it is vital to know which one will work for the surface you are repairing.
But, it is also worth noting that most modern car body fillers will have a special formulation and ingredients that allow them to be used on a variety of surfaces.
