Generally, the normal repair process for the appearance of aluminum alloy wheels is like this. First, thoroughly clean the inside and out before repairing, which is conducive to the contrast of paint color afterwards. In addition, after cleaning, the excess dust on the surface must be blown. clean. After all the preparations are completed, the restoration can be officially carried out.

The first step: wheel grinding

It is the same principle as car paint polishing. Repairing must first grind the burrs on the damaged area. This is to facilitate the next process of "scraping putty". Depending on the size of the wound, a special angle grinder or sandpaper can be used to polish the burrs. Of course, in any case, there is only one purpose, which is to smooth the burrs.

Step 2: Putty on the wheel hub

The putty used in the repair is not the putty used in car paint, it has a scientific name called "putty". There are several types of putty: plastic putty, glass fiber reinforced plastic putty, sheet metal putty, etc. Among them, sheet metal putty is also called metal putty, which is specially used for repair. When repairing, putty should be used together with corresponding curing agent, so that putty can play a fixed role. The putty must be polished after repairing. This is to facilitate the subsequent painting process. In addition, it is worth noting that putty can only repair small damaged scratches, such as deep pits, which need to be repaired with aluminum welding.

The third step: hub shielding

Like car paint spraying, masking is also required before spraying. Masking requires masking paper and masking paper. Everyone must understand the role of masking, which is to prevent paint from spraying on tires or other places. In fact, this is the same reason we need to bring an apron when we go to the barbershop to have a haircut.

Step 4: Spray paint the wheel hub

After the hub is covered, it is the most critical step of repair-painting. The paint must be adjusted before spraying. Usually, the quick repair shop has a computer system dedicated to the paint. After the initial color adjustment by the computer, in order to reduce the color difference, the technician usually needs to fine-tune the paint. After the paint is mixed, the paint can be sprayed. Spraying is a process of carefulness and technique. It requires certain technical experience. Not only will the color difference appear if the spray is not good, but the thickness of the paint will also be too different. This is why I don't recommend it. The reason why everyone paints by themselves.

Step 5: Paint the wheel hub

As the paint used in each store is not the same, there may be differences in curing methods. Generally, most spray paints are cured by baking lamps, also known as baking varnishes. There are some better quality paints, such as UV paint, which is cured by ultraviolet light. Regardless of the kind of paint, for general, the baking time is about 20-30 minutes.

Step 6: Wheel grinding and polishing

After the paint is completely dried on the aluminum alloy wheel, it can be polished and polished. This is the last process of this restoration. Grinding and polishing are mainly for the purpose of better fusion with other paint surfaces after spray painting, thereby reducing color difference.
