As someone who lives in a location with lots of snow and ice on the roads during the winter season, it is important for you to proactively prevent the growth of rust on the wheel wells of your vehicle. Once rust takes hold, it will eat through the metal wheel wells of your car and cause expensive body damage that will have to be professionally repaired at an auto body shop. To prevent the growth of rust on the wheel wells of your car, you can spray them with a rubberized undercoating paint using the air compressor in your garage and a specialized paint spray gun that is inexpensive.
To complete this project, you will need the following tools and supplies:
paint spray gun for rubberized paints
stiff scrub brush
dish washing soap
Follow this process to apply the protective undercoating:
Jack Up the Car and Remove Its Wheels
To apply the undercoating in the wheel wells, first, you need to remove the tires. Jack up your car on a flat surface and place it on top of jack stands for extra stability and safety. Remove all four tires.
Clean and Prepare the Wheel Wells for Painting
For the best final results, you need to spray the undercoating on to clean and grease-free wheel wells. To clean any gunk or road grease out of the wheel wells, mix a tablespoon of dishwashing soap in a bucket of hot water and scrub them with a stiff scrub brush. Once they are clean, then rinse the wheel wells with your garden hose or a pressure washer and let them dry.
Mask Off the Car's Body Paint and Chrome
Since over spray will damage your car's paint job, use masking tape and butcher paper to block off the paint and chrome areas around each of the car's wheel wells.
Prepare the Paint and Air Compressor
The rubberized undercoating paint needs to be shaken before it can be used. Vigorously shake the can and then remove its top. Insert the spray guns draw tube into the can and screw down the spray gun onto the can. Connect the spray gun to your air compressor and test that it is working on a piece of scrap paper.
Spray the Wheel Wells with Undercoating
Wearing personal protective equipment and a face shield, spray each wheel well using a slow and methodical motion. The undercoating should completely coat the surface. If the spray is not thick enough, then you should turn down the adjustment on the spray gun.
Put the Tires Back On
Finally, you need to put your car's tires back on and remove all of the paper. Congratulations, now your car's wheel wells are protected from rust damage!
