Best Car Body Fillers Buying Guide

How to Buy the Best Car Body Filler

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

1.1 Metal 

Metal fillers consist of aluminium metal parts and they are some of the most widely used fillers. These fillers will contain aluminum metal particles, and they have been in use since 1965.

They are known for their low moisture retention and do not shrink once applied which means you will not need to worry about reshaping. A good example of a fantastic metal filler is Permatex 25909.

Although they also provide a smoother finish when compared to other filer types, they are also more expensive.

Pros:

  • Low moisture retention
  • Smoother finish
  • They do not shrink
  • Harder when cured
  • Easy to work with

Cons:

  • Relatively more expensive

1.2 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. 

Because fiberglass filler like Bondo Glass 00272 is tough and long-lasting, it is very good for large scale repairs or when dealing with vehicles that have extensive damages.

The presence of fiberglass bits in this body filler and the fact that it requires heat treatment can make spreading it a little hectic, but things should get easier once you get used to it.

Pros:

  • Does not absorb moisture
  • Great for large scale repair jobs
  • Fast drying
  • Works with any paint type and color

Cons:

  • Can be a little hard to spread
  • Requires heat treatment

1.3 Lightweight 

Lightweight fillers like Evercoat 112 are easy to sand and  water resistant. They are more like metal fillers but with a more lightweight formulation.

These are often used as a final layer when repairing dents because they are not thick enough to cover large holes. However, they contain high amounts of resin to ensure the repairs last long enough.

Also, because these fillers tend to be easier to sand than metal or fiberglass, they have wider applications. Also, their lightweight nature makes them easier to handle as they can even be packed in papers.

Pros:

  • Smooth and premium finish
  • Wide applications
  • Easy to apply and sand

Cons:

  • Not thick enough for large holes

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.

#Step 1. Assess the Damage

Before you do anything you will first need to assess the damaged area and then use a hammer to try and restore the dented are as much as possible. What makes this an important step is that it will determine the filler type to use.

For small dents and scratches, you will only need to sand the area to give the  surface a rougher texture for better adhesion.

#Step 2. Pick the Right Product

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

If you are only doing small repairs, even the inexpensive lightweight body fillers will be more than enough, but for extensive repairs, you need metal or fiberglass body fillers..

#Step 3. Mixing

The third step is to mix the filler with a hardener. Here you will also need to make sure you have a good hardener like Evercoat FIB-359.

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 or a good spreader like Dynatron 358

Keep applying in layers while sanding down with sandpaper between dry coats until you get a perfect repaired or cured auto body.

FAQs

Q: What is the Difference between Body Filler and Putty?

A: Putty is typically softer than filler and it is hence only used in dealing with small impressions or in the final prep stages after applying filler. Filler can be used to fill out larger holes and cracks something which putty cannot do.

Q: Will Body Fillers Crack?

A: It is possible for body fillers to crack when not applied properly. But provided you do not apply it to dents that are deeper than 1/8-inch and give it enough time to cure, the filler should not crack.

Q: What Kind of Body Filler is Used on Overhaulin?

A: They use Evercoat, which also happens to be what many other auto repair TV shows seem to prefer to use.

Q: How Big of a Dent can I Fill with Bondo?

A: Bondo can really fill up those large and troublesome holes. However, Bondo seems to work best on dents up to 1/4-inch deep. That said, the particular type of Bondo that you are using also determines the size of dent you can fill.
