Conclusion

There are a few different types of auto body filler that can be used to repair rust. The most common type is polyester filler, which is a two-part resin that is mixed together and then applied to the affected area.

It dries quickly and can be sanded down to create a smooth, level surface. Another type of filler is epoxy, which is a stronger, more durable option that is best used for larger areas of damage. It can be more difficult to work with, but will create a stronger repair.

Sharing is caring!
