Should I use Bondo or wood filler?

Bondo and wood filler are both used to fill holes and cracks in wooden objects. They are also used to smooth out rough edges, but Bondo is more durable than filler.

Both products come in many different colors so you can choose the one that matches your project best. The choice between using one or the other depends on what you want: a permanent fix or something temporary.

Which is better wood filler or Bondo?

Bondo is a polyester resin that’s used to fill holes and cracks in wood, fiberglass, and metal surfaces. Bondo has been around for almost 80 years, and it’s still one of the best products on the market for amateur car enthusiasts looking to restore their classic rides.

Professional mechanics also use Bondo because it’s easy to work with, dries quickly, and produces excellent results.

Bondo comes in many different colors, including black—which allows you to match your existing paint job—and white if you’re painting over damaged areas on your car’s bodywork.

It can be applied with a brush or roller depending on what kind of surface you’re working with (if its metal then uses a brush). The thicker the layer that you apply then sand down afterward will determine how smooth or rough your finished product will look when dry (more sanding = smoother finish; less sanding = rougher finish).

Can I use Bondo instead of wood filler?

Bondo is a polyester resin that is used to bond and fills large holes, small cracks, and dents in wood. You can also use Bondo to fill holes in metal, fiberglass, and other materials.

Bondo cures when it is exposed to the elements of weather, sun, and heat. The curing process takes anywhere from 10 minutes up to an hour or more depending on how much product you are using at once.

What is the difference between Bondo and filler?

Bondo is a polyester resin that works as a filler and glue. It’s thick, so it can fill cracks in your car with ease.

Bondo has two parts that need to be mixed together before use (the hardener and the base).

Once mixed, Bondo is flexible and strong enough to fill holes that would otherwise require a new panel of sheet metal.

Bondo bonds well with steel, aluminum, and fiberglass surfaces like those found on cars or boats. It also works well with wood as long as you aren’t using it inside the house—Bondo contains chemicals that may cause health concerns if inhaled or ingested over time.”

What works better than wood filler?

Bondo is a good choice if you are looking for something that has more durability and strength than wood filler.

It is also easier to work with than wood filler, which means it will take less time to get the job done.

However, it is more expensive than wood filler and not as messy either.

Is wood filler permanent?

If you’ve been around cars long enough, you’ve probably heard the term Bondo. Many people confuse Bondo with wood filler, which it’s not.

Bondo is a type of plastic and can be used to repair holes or dings in your car’s bodywork. The main difference between Bondo and wood filler is that Bondo will melt if you use too much heat on it; this means that any surface that needs to be painted needs to be sanded before painting so that the paint doesn’t peel off when it heats up under the sun or in an oven.

Wood filler is made out of sawdust mixed with glue; this mixture makes up for whatever shortcomings there may be when using other types of fillers like plaster-based ones because they’re weaker than bonding agents found in wood fillers—which means that they won’t crack after drying either!

Do you have to use a hardener in Bondo?

Bondo is a two-part epoxy putty that can be used to fill holes and cracks in wood, metal, plastic, and other materials. It’s also great for sealing or filling large dents on your car or boat.

You apply Bondo by mixing equal parts of hardener and resin with a trowel until you have a thick paste-like consistency.

You then spread the mixture into the damaged area and allow it to set up before sanding it smooth with an orbital sander or sandpaper wrapped around a block of wood.

Alternatively, you could use pieces of cotton cloth over an electric drill bit for more control when applying Bondo by hand.

Do you have to Prime Bondo on wood?

When you are using Bondo wood filler, you can prime the surface before painting.

Bondo does not paint. It is a filler and therefore has to be primed before it can be painted.

Bondo is very durable, but it is important that you prime the surface first because without priming the Bondo will not adhere to your existing wood as well as if you were to prime first.

When should I use Bondo?

Bondo is a filler, not a wood putty. It’s used to fill in holes and dents in auto body panels and is also used to fill in cracks in plaster, drywall, and masonry. Bondo can also be used to fill cracks in concrete (it’s actually quite good at this).

Conclusion

Bondo is not the best option for your wood filler. It is better to use a product that will provide you with a longer-lasting result and better protection from moisture.

If you are looking for something that lasts longer than Bondo, then you should consider using another type of material such as epoxy putty or polyester resin.
