Fillers & Putty

Putty and Body Fillers

Anyone who is repairing dents or restoring a car or vehicle knows it is very important to use the right body filler or putty. When you use it the right way, it can't go wrong easily. Keep in mind that certain putty's require a catalyst, activator or hardener.

Different Types of Putty

Putty's are generally a polyester resin based filler with catalyst or hardener. Body fillers fall into three categories:

• Fine body fillers

Fine Putty

Fine body fillers are a lightweight substance or putty that spreads easily and cures in about 20-25 minutes. While not appropriate for use on galvanized steel, fine putty's are perfect for repairing minor dents and scratches. Fine putty can be used to fill pin holes, small irregularities, small paint damages or scratches. They sand easily to blend in with the rest of the vehicle once primed and painted. Standard grade also offers the least stain-resistance.
