How to Put Body Putty on a Car

Repairs to a dent, ding or rusted area on your car need more than body filler for them to look professionally done. Body filler is porous and soaks up primer, paint and moisture, creating pinholes and making the area noticeable after the body work and paint is complete. To prevent this, you can use body putty over the filler. Putty sands easier and is a finer material to work with. Applying body putty is similar but not exactly the same as applying body filler.

Instructions

1

Scoop a small amount of body putty out of the container and onto the palette. You only need enough putty to put a very thin coat over all of the body filler used.

2

Squirt the hardener directly onto the putty and quickly mix it with the plastic squeegee. Use a dime-size amount of hardener for every baseball-size amount of putty used. Use the squeegee to fold the putty and hardener together until everything is one solid color, not marbled.

3

Use the squeegee to spread a thin layer of body putty over the areas of the car with dried and sanded filler. Use the putty to perfect any areas of the filler that arent completely level and smooth. Let the putty dry for 30 minutes.

4

Sand the dried putty with 320-grit sandpaper and then clean the area and prepare it for priming and painting.
