Repair the first step: grinding, and car paint grinding is the same principle, repair the wheel first to wear the Burr to smooth, this is to facilitate the next process of "scraping putty" and prepared. Depending on the size of the wound, the Burr can be polished using a special angle grinder or sandpaper, of course, in any case, there is only one purpose, which is to smooth the burr. 2.

There are several types of putty: Plastic Putty, glass fiber reinforced plastic putty, metal putty and so on, among which, metal putty is also called metal putty, it is specially used to repair the wheel. Repair, putty with the corresponding curing agent to use together, so that putty can play a fixed role. The putty is repaired and then sanded accordingly, in order to facilitate the subsequent painting process. In addition, it should be noted that putty can only repair small areas of damage scratches, such as pits deeper defects, need to cooperate with the welding of aluminum to repair. 3. Step 3: Masking, like car paint, the wheels need to be masked before painting, and masking paper and masking paper are used for the wheels. The function of shielding, as is presumably well known, is to prevent paint from being sprayed on tyres or elsewhere.

When the painting is finished, the painting can be sprayed. The painting is a meticulous and manipulative process, which requires a certain amount of technical experience. If the painting is not done well, not only will the color difference occur, but also the thickness difference of the paint surface will be too large, that's why I don't recommend spray painting. 5. Fix Step 5: Paint, because different stores use different paint, in fixed-line method may also be different. In general, most spray paints are cured with a baking lamp, also known as a baking varnish. There are some better quality paint, such as: UV paint, is the use of UV light curing. And regardless of which kind of paint, for the average wheel hub, the paint time is about 20-30 minutes. (UV Paint is an abbreviation for Ultraviolet Curing Paint, or UV curable Paint. Under the irradiation of ultraviolet light, it can decompose the initiator, produce free radical, initiate the reaction of Resin, and instantly solidify into a film. 6. Repair Step 6: Grinding, polishing, and wait until the paint completely dried, you can Polish, polishing, this is also the wheel repair process. The purpose of sanding and polishing is to reduce the chromatic aberration by better fusing the finished paint with other finishes. At this point, all work on the hub repair is complete.
