Covering this too much secret
Tips: At present, most of the social repair shops do only use 3 steps. That is: putty (commonly known as 'puffed put'); top coat; varnish. Because as long as these 3 steps are completed, you can basically achieve the 'whitewashing' Purpose. However, due to the lack of necessary core steps (such as: epoxy primer, midway primer), or the process is not up to standard (such as: insufficient curing time, insufficient temperature during painting, poor paint quality, etc.), for a long time, Or encounter some bad weather or environment, it is likely to cause chromatic aberration in your car, serious patent leather drum bag; paint, and then rust.
To sum up, as mentioned above, it is necessary for the case where the damage is relatively large. For these paintings that require sheet metal repair or disassembly, it is not an hour or two of work. Some repair shops do paint quickly, why fast? Many steps are omitted, and naturally it is faster, so if you choose 4S shop paint, sometimes you will be considerate for a long time.
