STEP ONE: CLEAN WHEELS
An all important step for an Alloy wheel repair is to clean the wheel(s) thoroughly to expose all the areas that will need to be treated and repaired. In most cases, we will not need to remove the wheels from the car as all damaged areas are exposed, The car is generally raised using a jack in the appropriate spot.
STEP TWO: ROUGH SANDING
The next step is to rough sand away the surface of the alloy wheel. This removes all damage and prepares the surface for the following applications of grits. If the area is not properly prepared with rough sanding, you will find your alloy wheel repair will not last.
STEP THREE: FINER SANDING & ALLOY COMPOUND
Finer sanding is a delicate process where the aim is to create the smoothest possible surface, While still retaining enough surface prep to allow paint to adhere. If any shape is lost to your wheel due to rough sanding then soft sanding is used to bring that back, Sometimes filler is required however This step is, generally optional, depending on how deep the gouges or scratches might be.
Filler is almost always a last resort.
STEP FOUR PART A: PAINT APPLICATION
Once the surface has been prepped to an acceptable standard, an adhesion promotor is then applied to the bare alloy, Followed by 2-4 coats of base coat colour ( matched to your original wheel paint within 2-5 shades ) then it is given a few moments to tack off, then 2-3 coats of a clear is applied for the required result to blend seamlessly into your original finish.
STEP FOUR PART B:
If your rim is a polished lip, Once the surface has been sanded and all voids / pin holes removed it will be sanded with various grits to achieve a great luster finish that matches seamlessly with your original polish, then a coat of 2K clear is then applied to help maintain the luster of the polish! If required at a later date it MAY require a polish using an external metal polish ( this can be applied by hand by yourself )
