Before you begin to spray a fresh layer of paint, you will need to use a car body filler for filling defects panels. Auto body fillers are designed to bond with a range of automotive components and bare metal for repairing damage.
Body filler is very important when used properly, it can make bodywork repairs straightforward. It is far less time consuming and expensive than replacing the entire body panel with a new part.
Once you have filled the damaged panel with a body filler, you can then apply a primer, base coat and finish up with an automotive clear coat.
