For the Best Results, Get a Compressor and Paint Sprayer


Many car body repairs will require you to fix and re-touch a section of your car. Once you have matched the paint (it’s best to go straight to the manufacturer for the paint), you need a high-quality paint sprayer for auto body work, preferably with a light enough touch to easily apply a few coats over several days. Take your time with these finishing car body repair steps, and check out our guide on paint sprayers!

Use a Sanding Tool Instead of Your Hands


Sanding is important when repairing car body dents, dings and scratches, as well as buffing out a new paint job. However, use a sanding block or a sanding tool rather than your hands for auto body work. Sanding with just your hands often results in “natural” grooves and errors, sometimes even when you’re very careful. For a smooth finish, consider buying an all-purpose sander.

Finishing Glaze


Finishing glaze serves two important purposes in auto body work. First, if you have very minor flaws or scratches in your paint coat, finishing glaze may be able to fix the problem (make sure you choose the self-leveling kind). Second, for larger repair projects, glazing is an important step before applying the final coats of paint to a repaired surface.

Fix Windshield Cracks With the Right Kit


Just as chips in your paint can cause rust, chips in your windshield can spread out into annoying damage, so it’s best to fix them right away. The good news is that you can order or pick up windshield repair kits that use resins to block the crack or chip before it causes more damage. With the right tools, you can also replace side power windows!
