Best Car Body Fillers Buying Guide

How to Buy the Best Car Body Filler

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.

#2. Compatibility

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.

#3. Ease of Application

Any car body filler that you choose should be easy to apply whether you are doing it for the first time or are a professional. 

An easy body filler to apply is one that is easy to mix and has a nice consistency for easy spreading. Also, those that come with a spreader and detailed instructions will give you an easier time.

How to Use Car Body Filler

How to Use Car Body Filler

Finding the best car body filler is always the first step as you will still need to apply it correctly. And while the application will depend on the particular filler type you are using, the following are the basic steps you need to follow for most fillers.

Based on your findings on step #1 you can now proceed to pick the appropriate product for repairing the damage at hand.

The third step is to mix the filler with a hardener. In this step, make sure to maintain the right ratio to get perfect product consistency. Mix the products at a ratio of 100:2 or according to the manufacturer's directions..

Once it forms a nice blend, check the consistency and make sure it is smooth enough to apply or else it will not dry properly or cure the dents or scratches nicely.

#Step 4. Application

Apply the filler smoothly in even coats and shape it using the applicator. Keep applying in layers while sanding down with sandpaper between dry coats until you get a perfect repaired or cured auto body.
