Body Filler
Body filler is a type of putty that is used to fill in dents, scratches, and other imperfections in the body of a car. It is made from a variety of materials, including polyester resin, fiberglass, and metal. Body filler is available in two forms: catalyzed and uncatalyzed. Catalyzed body filler cures quickly, while uncatalyzed body filler takes longer to cure.
The type of body filler you use will depend on the severity of the damage you are repairing. For small dents and scratches, you can use a catalyzed body filler. For larger dents and holes, you will need to use an uncatalyzed body filler.
