How Long Does Bondo Last On A Car

Bondo is a type of body filler typically used to repair automobile bodies. Unlike other types of fillers Bondo is designed to be easily sanded and painted making it a popular choice for do-it-yourselfers and professional body shops alike.

But how long does Bondo last on a car?

Unfortunately there is no definitive answer. The lifespan of Bondo will depend on a number of factors including the quality of the Bondo itself the skill of the person who applied it the type of car it is being used on and the conditions the car is typically driven in.

With that said in general you can expect Bondo to last anywhere from 3 to 5 years on a car. Of course if the Bondo is applied poorly or to a particularly rusty spot on the car it may not last quite as long.

If you’re thinking about using Bondo on your car be sure to do your research and choose a high-quality product. And if you’re not confident in your ability to apply it properly it’s always best to leave it to the professionals.
