Some of the car alloy wheel have scratch,how does the alloy wheel repair .
A slight scratch can be repaired by itself:
Step 1: Clean the hub. We can use paint diluent to wipe around the scar and remove dirt. The deepest part of the scratch is difficult to remove dirt, so you can use toothpicks to clean it thoroughly. In cleaning, in order to prevent the improper application of paint on unrelated parts, it is best to carefully stick the adhesive paper around the scar.
Step 2: The owner tidies up the brush tip and coats the damaged hub with decorative paint. After the paint is dried, it protrudes slightly to facilitate the owner's observation.
Step 3: After the main decorative paint is completely dried, apply it with soapy water dipped in water-resistant paper to make the surface smooth. Then use the mixture to polish and wax.
Step 4: If the car owner finds deep scars on the hub, and must observe whether the metal surface is exposed, if the metal surface is not visible, it will not rust, you can concentrate on painting.
Use the tip of the pen bit by bit and wait until the paint is completely dry. If metal is found to be exposed, it's better to replace it.

Matters needing attention:
Daily maintenance is also indispensable, when the hub temperature is higher, it should be allowed to cool naturally before cleaning, must not use cold water to clean. Otherwise, the aluminum alloy hub will be damaged, and even the brake disc will be deformed, which will affect the braking effect. In addition, cleaning the aluminum wheel hub with detergent at high temperature will cause chemical reaction on the surface of the hub, lose its luster and affect its beauty.
When there is tar on the hub which is difficult to remove, if the general detergent is not helpful, you can try to remove it with a brush, but do not use a hard brush, especially iron brush, in order to avoid damaging the surface of the hub. Here, to introduce to private owners a partial formula for tar removal: that is, the use of medicinal "Huoluo Oil" rubbing, can achieve unexpected results, try it. Wheel hubs should be cleaned regularly when the vehicle is in wet or near the seashore to avoid salt corrosion on the surface of aluminium. When necessary, after cleaning and cleaning, the hub can be waxed and maintained to keep its luster forever.
