When used properly, bondo- or body filler- is a perfect material for repairing dents, scratches, and other bits of damage to a vehicle quickly and seamlessly. But applying filler incorrectly can lead to an uneven body that will cost you even more to repair.
How long does Bondo last on a car?
In most cases, Bondo filler lasts for two to three years. There are car owners who have had Bondo hold on to their vehicle’s bodies for even eight years. If you want it to last that long, then you need to apply it correctly and thoroughly follow the manufacturer’s instructions.
Is Bondo better than wood filler?
The biggest advantage of using Bondo over a regular wood filler is the short dry time. Wood filler can take hours to dry and require more than one coat. Bondo dries in less than 30 minutes and only requires one coat! This means more projects in less time.
Which is better Bondo or fiberglass?
Fiberglass is More Durable than Bondo
The first key difference between these two is in regards to durability. Fiberglass is way stronger than Bondo resin. Therefore, when you use fiberglass filler, expect it to outlast car parts that have Bondo.
Do professionals use Bondo?
Professional, high quality shops use body filler on custom cars and restorations continuously. Even as a DIY’er, using body filler on your every day vehicle or project car can be a fantastic option, so long as body filler is used correctly.
Is Bondo permanent?

How long does a rust repair last?

What’s the strongest wood filler?
Coming in as our number one pick is DAP Plastic Wood. This all-purpose, solvent-based wood filler is formulated with real wood fibers. It looks and acts like actual wood, except once it hardens, it’s three times as strong.
Do you need a respirator for Bondo?
Depends on where you working with it. If it’s outside, you can just use a regular old dust mask, but if it’s in a garage, I’d recommend a respirator. These kind of chemicals can cause nausea, headaches, etc, and long exposure can cause nerve damage and death.
Can you put wood filler over Bondo?
To fill wood, you need a product that is specifically designed to bend and flex the way wood does. Just like caulk is too flexible to effectively fill large gaps in wood, Bondo is too stiff to do the same. When Bondo (or any auto body filler) is used to patch wood, it fails in a very short time.
