is Bondo better than wood filler?

Bondo, or auto body filler, is a popular product for repairing and restoring vehicles. It has many uses in the home as well.

Bondo can be used to fill holes in wood, masonry, and other surfaces, but does it work better than wood putty? The answer depends on the material you are working with and what your goals are for the project.

Can I use Bondo instead of wood filler?

Bondo is a two-part epoxy that works well for filling holes and cracks in wood. It’s not a replacement for wood filler, but it can be used on its own or in combination with other materials.

If you have a hole in your garage door, Bondo is an excellent choice because it will fill the hole and prevent water from seeping through to the interior of your home.

Is Bondo as strong as wood?

Bondo is stronger than wood. Bondo has a higher tensile strength than most other fillers, including wood filler. In fact, one of the ways that Bondo can be used to repair cars is by filling in cracks and holes in sheet metal with it before painting over it.

The hardened bondo becomes part of the car’s shell and gives it extra strength and durability.

When you are working on something as big as a boat or truck bed, having a strong base material is important because if you want to build something strong enough for daily use or occasional heavy use (think hauling trees), then using something with more permanent qualities like fiberglass or steel seems like an obvious choice.

What is the difference between Bondo and filler?

Bondo is actually a two-part epoxy, meaning it’s a little more complicated to use than your average wood putty. However, the benefits of Bondo are many: it’s stronger and more durable than most commercial fillers, meaning you won’t need to keep applying more and more filler over time.

It also cures faster than other commercial fillers, which means you don’t have to wait around for hours before you can sand your project smoothly again.

Plus, even though Bondo is technically a “filler,” it doesn’t have the same consistency as something like wood putty (which is basically just like clay).

This means that when you apply it to an area where there are gaps or holes in your surface—say from nicks or scratches—you can spread Bondo out into thin layers without having to worry about creating air pockets that could weaken its adhesive strength later on down the road when you’re ready for sanding work.

What is better than wood filler?

Bondo is a two-part epoxy that can be used to fill holes and cracks in wood. It’s stronger than wood filler, so less of it will be needed to fill the same size hole. Bondo is also waterproof and sandable.

Do you have to Prime Bondo on wood?

You can use Bondo without primer, but you’ll get better results if you prime the wood first. Bondo doesn’t always adhere well to the surface of wood, so the primer will help it stick better.

It will also prevent cracks from forming in your finished product because it creates a good base for bonding.

If you don’t have any matching paint left over from when you painted the rest of your piece, using a primer as a base coat is an easy way to get a perfect match.

If you want to match the grain and texture of your wood in addition to color, then priming before applying Bondo is going to be more work than just painting over everything with one color at once.

However, it could save time later on by making sure that all newly applied layers have great adhesion right away instead of having some areas peel off easily while others stay stuck firmly where they belong!

Is Bondo waterproof?

Bondo is not waterproof, but it is water-resistant. Bondo has a film-forming resin that creates a strong bond with the substrate so that when it cures, its surface becomes hard and rigid.

It also protects against corrosion as it does not allow moisture to seep into the wood or metal surfaces. However, Bondo doesn’t provide any protection from water penetration; you can only use it in dry environments like garages or workshops.

Bondo isn’t painting either; therefore you cannot expect its appearance to last long outside your home where there are harsh weather conditions such as rain and windy days (especially during winter).

If you’re looking for something that will protect your outdoor furniture from water damage then use exterior-grade paint instead!

Can you use Bondo to repair rotted wood?

Bondo is not a good choice for repairing rotted wood. However, it can be used to repair small holes and minor dings in your vehicle’s body panels. Bondo is not a good choice for repairing major dings.

When should I use Bondo?

Bondo is a great solution for repairing small dings and dents in metal, wood, and fiberglass. It’s also a great choice for filling in small holes, cracks, and other surface imperfections on all of these materials as well.


Bondo is a great product that can help you repair any damage to your vehicle. It’s important to choose the right type of Bondo for the job and follow instructions to ensure that your project is successful.
