How to Thin Car Body Filler
What is Car Body Filler?
Car body filler, also known as body putty or bondo, is a type of automotive repair material used to fill in dents, scratches, and other imperfections in the body of a car. It is typically made of a combination of resin, hardener, and fillers, and is applied to the damaged area with a putty knife or spreader. Once applied, the body filler will cure and harden, filling in the imperfection and creating a smooth, even surface.
Why Would You Need to Thin Car Body Filler?
There are several reasons why you might need to thin car body filler. One reason is to make it easier to apply. Thick body filler can be difficult to spread and may not fill in small imperfections as well as thinner body filler. Another reason to thin body filler is to extend its working time. Body filler typically has a limited working time, meaning that it must be applied and shaped within a certain amount of time before it begins to cure. Thinning the body filler can extend its working time, giving you more time to work with it.
