It is natural to want to repair this damage, but many people make the mistake of choosing the wrong paint job or car body filler for their car — so here are the ones that work the best — eight choices to consider in more detail.

Pros:

  • Easy to use
  • Self-leveling
  • Great filler for small holes

Evercoat is one of the best names in body fillers, and with good reason. With a proven track record in the auto repair industry, you can trust that Evercoat is putting their best products forward.

This particular filler is the product you’ll want to reach for if you need to fill a minor dent or hole in the body of your vehicle. This is due to its ability to expand at a relatively low temperature. When used in combination with a hardener, this product can expand across a relatively small area at a rate of 2 inches every minute.

It is also considered a self-leveling material, which means you can use it with little to no preparation. This makes it a great product for repairs performed in an emergency. You will simply need to apply the product directly to the body of your car and allow it to self-level. It also adheres to any number of surfaces, allowing you to perform a wide range of repairs requiring varying levels of expertise.

Evercoat�s creme-based filler is available in 4oz, 8oz, and 1 gallon tub capacities and comes in a variety of colors. The huge variety is due to the fact that filler will work over previously painted surfaces, while other fillers will not.

On the topic of durability, Evercote is proud to mention that their filler can withstand a pressure washer and hot water. That is quite an achievement considering most body fillers can’t even handle a garden hose.

This filler is easy to use as it requires minimal additional curing work and can be sanded in 30 minutes. Although the curing time is shorter than many fillers, we still recommend waiting 7 days to sand the material. That being said, you can start painting that new dent in a little over a day.

Frequently Asked Questions (FAQ)

What is the strongest body filler?

Aside from body work experience, common sense with regard to application techniques is a major factor in achieving a successful repair. According to the pros, the following are the most important factors in achieving a professional looking repair: apply a thin, even coat of filler with a high-quality caulk gun, feather the edges of the repair, sand smoothly, and apply a minimum of 4 coats.

How big of a hole can you fill with Bondo?

The amount of steel you can repair depends entirely on the size of the hole you're filling, as well as the size of the bondo container you're working with.

Typically, one container of bondo is the equivalent of about 2-3 quarts of liquid. Bondo is sold in quart containers. So, if you have a particularly large hole in your bodywork, you might need to buy more than one container.

If you have a hole that’s large in diameter, you might want to look into a fiberglass repair kit instead of using bondo.

What is the difference between Bondo and body filler?

Bondo is the original and most widely known of the body fillers. It is the preferred filler for most, due to its quick drying time and long-lasting results. It's superior to bondo, also known as body putty, and fillers like it because it dries with a smooth finish so you don't have to sand it again before painting.

While more expensive than Bondo, it is worth the extra dollars for the superior results. Bondo can really mess up your body work. Plus, many people have allergies to the chemicals in it, which will also affect your painted results.

Does body filler last long?

Body filler is a type of epoxy that is commonly used to repair damaged areas on automobiles. It is used both by professional mechanics and do-it-yourself repairmen. One of the best things about body filler is that it is extremely versatile. It can be used on pretty much any area of the vehicle, and it can almost any shape. This allows you to use it to fill in holes, repair broken mouldings, and fix a variety of dents.

Body filler isn’t a permanent solution, however, and it won’t last as long as other types of auto repair. You won’t be able to get away with using body filler just one time. You can use body filler for one or even two repairs, but after that it must be removed and the area repaired. It cannot be used over and over as a permanent solution.

Conclusion

Have you had a run in with someone's pebble or rock, either from your front end or the rear of your car? If so, then you'll know that sometimes the damage caused isn't just superficial damage – often, the car will need a panel replacement. In many cases, getting this kind of damage repaired can be expensive and in many cases (especially if it's minor) the owner of the car may decide to leave the panel without repair. If the damage is minimal enough that they might not want to bother with it, but if you had body filler at home, you could just fix it yourself (or at least try).
