If you have a scuffed aluminum wheel, it can be restored with simple techniques. Here you’ll find five steps that can help you repair polished aluminum wheels to eliminate the curb rash.
Find Out If the Rim Comes with A Protective Coating
To find out whether rim has a clear coating, you have to first sand the damaged spot on the rim with a coarse-grained sandpaper with 220-grit. If the dust generated is white against the gray, your wheel rim has a clear-coating that must be removed to reach the curb rash.
Remove the Clear Coating
Now you need to remove the clear coat through-out the rim so that the refinished spot ends up having the same color and texture as the rest of the rim. You may have to buff the rim with the help of a 220-grit sandpaper making use of the firm strokes. When the dust you are grinding, turns gray instead of white, it means that the clear coating has been removed.
Smoothen The Scratches
With the help of an 80-grit sandpaper, and working up to 220, just go over the abraded spot on the wheel rim to smoothen out the scratches. Once you are done, the most obvious scratches and gouges go ahead and make use of a feathering motion with the sandpaper, this time with 400-grit sandpaper, to just half inch beyond the rash to blend in the damaged area. It will ensure that it will go with the rest of the wheeled rim.
Just go ahead and employ the steady pressure when sanding with this paper to level any of the remaining edges. Make use of the angular strokes in the outward direction front the center of the rash. Finally just wipe-off the dust from the rim with a cloth every time.
Refine the Surface
To this end, you have to choose a very fine grit. Make use of the light pressure and a circular motion making the use of the dry sandpaper covering the entire spot. Just focus on blending the edges, and smoother out the surface texture. It might take longer; you will get the desired results.
Apply Aluminum Polish
Take the polish with a soft cloth and work it deep into the sanded area. You may have to apply a lot of pressure while rubbing in the polish.
In this way, you can repair polished aluminum wheels and ensure that they are working normally again.
