Repairing curb rash on wheels. This method is for those who want to save considerable money as opposed to getting them professionally done at a wheel repair shop. Total investment is about $40 dollars. The results speak for themselves.
1 Can of Automotive Paint primer
1 Can Paint thinner
1 Can of Base Coat [appropriate for your wheel]
1 Can of Clear Coat
1 Pack of Sand Paper from 180 - 1500 Grit
1 Tube of Spot Bondo
1 Putty Knife
1 Old Newspaper
Two days for paint to dry. Total working time about 2 hours.
Difficulty: 3 out of 5
Make sure the wheel is completely clean and free of any polish, etc. I would use paint thinner to accomplish this. Prepare the damaged area by lightly sanding with a very fine grit sand paper or steel wool. Do not take the finish down past the clear coat. This process ensures that the surface will be ready to take paint and Bondo.
Now cover the entire wheel where you won't be working with news paper to avoid overspray. The picture below shows the area that needs work.
If possible, do this with the tire off the wheel. I did not have the luxury at the time, but it would have made things a lot easier.
Start off by applying thin coats of bondo from the tube. You can use a putty knife to apply. Most damage requires two layers of bondo. Each application requires about 10 minutes to dry. Bondo is dry when it turns from the darker redish shade down to pink. Use 320 grit until the roughness and sharp ridges are gone visibly and to the touch. Then use 600 to finish. If you are a perfectionist end with fine grit (1000) .
Apply small amounts at a time to fill in slowly. Too much at once will result in sloppy results, or even cracking of the filler.
Using a sweeping motion, holding the spray can about 10 inches out from the wheel surface, taper or feather the primer from the damaged area out. If there is over spray, make sure you clean it off with the paint thinner right away. When the primer is dry sand it lightly with 600 grit sandpaper until it is smooth.
Now, take out your sample sheet of paper get comfortable spraying the color coat. Practice holding the can about 6 - 8 inches (or how much the can says to use it) from a sheet of paper and practice painting using a sweeping motion. Remember when painting, that for the base coat, less is more.
It is far better to apply multiple thin coats than one thick coat which could result in dripping, runs and other ugly problems. Once you are comfortable, apply the base coat. It should only take two coats to get the job done. Remember use the gentle sweeping motion when painting.
You do not need to sand between each base coat. If you have not used a spray paint can before, search YouTube for How-to's. Watching technique of others helps a lot. Remember to clean up the overspray right away with the paint thinner.
After a day of letting the wheel color to dry apply the clear coat. Clear coat concept is the same as the previous step.
After 2 light coats of clear applied. Color set in nicely.
Put the wheel on and enjoy the finished Results....
