Car Body Filler Showing Through Paint
What is Car Body Filler?
Car body filler is a material used to repair dents and other imperfections in car bodies. It is typically made of a resin and a hardener, and is applied to the damaged area and allowed to dry. Once dry, the filler can be sanded and painted to match the rest of the car.
Why Does Car Body Filler Show Through Paint?
There are several reasons why car body filler may show through paint. These include:
* The filler was not applied properly. If the filler is not applied evenly or if it is not allowed to dry completely, it may create a weak spot in the paint that will eventually allow the filler to show through.
* The paint was not applied properly. If the paint is not applied evenly or if it is not allowed to dry completely, it may not adhere properly to the filler and may eventually peel or chip, revealing the filler underneath.
* The filler has been damaged. If the filler is damaged after it has been applied, it may create a weak spot in the paint that will allow the filler to show through.
How to Fix Car Body Filler Showing Through Paint
If car body filler is showing through paint, there are several steps that can be taken to fix the problem. These steps include:
* Sand the area around the damaged paint. This will create a smooth surface for the new paint to adhere to.
* Clean the area with a degreaser. This will remove any dirt or grease that may prevent the new paint from adhering.
* Apply a primer to the area. This will help to create a strong bond between the new paint and the existing paint.
* Apply new paint to the area. Be sure to apply the paint evenly and allow it to dry completely.
If the damage to the filler is extensive, it may be necessary to replace the filler. This is a more complex repair that should be performed by a qualified auto body technician.
