Step 1: Prepping the Chrome Bumper Surface
This is the first important process of painting a chrome bumper. Get the bumper prepared is not that easy. It is also an entire process. Now, to prepare the chrome bumper, do the following things.
- Separate the Vehicle Bumper
Separating the bumper from the vehicle is a wise idea before you start painting on it. It will make the preparation and painting process easier. To separate the bumpers, loosen the bolts and screws with what they are attached to the vehicle. So, this way you can remove both front and rear bumpers of your vehicle.
- Wash the Bumper
Second, it’s time to wash the chrome bumper. Use soap and water for washing purposes. There could be a lot of dirt, dust, and fingerprints on the bumper surface. So, washing it thoroughly is the only way. Otherwise, the paint will not result in a great finish on the dusty surface.
- If the Bumper Is Rusted, Remove It
Chrome is prone to be rusted soon compared to other metal objects. So, you can also have a rusty bumper. If so, then getting the rust clear is highly recommended. To remove the rust, you can use several products including natural ones.
- For this, you can mix a thick paste of baking soda and vinegar. Apply the mixture to the rusty area and let it sit for up to 5 minutes. By this time, it will react with the rust particles and loosen them from the chrome bumper.
- If some rusts still pop up, apply the mixture again.
- Completing removing rust, wash the bumper again with soap and water.
- Time to Sand the Bumper
For painting chrome bumpers, you need to make a proper paintable surface. Hence, sanding the chrome bumper is necessary. You can use either a dual-action sander or sandpaper for this purpose. Coarser sandpaper with a grit of 40 or 60 should be selected first. To remove scars, flaking, and deep spots, this sandpaper will help.
Again, to fix small scars, you can get a paper with 80 or 120-grit. Now, to get a finer finish, you can use a paper with a grit of 300-600. This will ensure a smooth surface for painting over.
- Wipe the Chrome Bumper
When you are done sanding the bumper evenly, you need to wipe down the dust. You can also use wax remover and grease to clean off additional contaminants including oil, dirt, grease, and all. After cleaning with wax remover, dry the bumper wiping with a clean and dry rag.
- Cover the Areas You Don’t Want to Paint
Lastly, cover up the places of the bumper where you do not want to paint. To come up with your customized design, you can cover the areas using a plastic or painter’s tip. Precisely seal the tape so that the edges are firmly pressed down.
Step 2: Prime the Chrome Bumper
- Wear Safety Gear and Set Up Your Workstation
Ensure safety, and protection gear are a must since the painting process is not very healthy. The ventilated environment will be required as well. Otherwise, aerosol sprays and fumes can affect the respiratory system. Wear gloves, a mask, and a respirator or an exhaust ventilation system for ensuring safety precautions.
- Spray Self-etching Primer on the Chrome Bumper
Using a self-etching primer, in this case, brings the expected result. It helps in better application of regular primer on the bumper later. Spray at least two to three coats of the self-etching primer evenly. But make sure you spray another coat when the previous one is dried completely.
Each coat won’t take more than three minutes to dry. But let the last coat on the chrome bumper sit for about four hours.
- Spray Regular Primer on the Bumper
After applying self-etching primer, apply the regular automotive primer. It will hold a strong bond between the paint and chrome. It will also prevent rust and corrosion from the object. Apply two to three coats of this primer in the same previous ways.
However, drying time varies for different primers. So, check the time and let it sit according to that.
- Sand Again the Surface
It is time to sand again but not on the chrome surface. When the primer is fully set on the bumper, you can sand it to make it smooth. Grab 400 to 600-grit fine sandpaper and sand carefully.
Tip: If you accidentally sand the chrome surface, apply the primer again in several coats. Then let it dry and sand again.
- Wipe away the Dust
After sanding, wipe away the produced residue and dust from the surface. Be careful in this step also as there are chances of erasing the primer as well. you can use wax, grease, water, and anything like that to wipe it.
Step 3: Apply the Paint
- Know and Practice the Spraying Technique
Now that we have come to the most crucial part, you better have some practice. Spraying a spray gun on a metal piece is a good idea for practicing. Make sure you are holding the spray gun 15.2 cm or 6 inches away from the metal surface.
Tip: In case you are using heavy paints, drips occur. If they occur use wet sandpaper of 2000-grit to sand them down gently.
- Spray Paint on the Bumper
After enough practicing when you are confident enough, apply the spray gun on the bumper. Make a light and even layered coat of paint. It will require 3-4 even coats. Do not apply another coat until the previous one dries properly.
