Car paint polishing putty should be smooth, of course, when scraping putty, it must be smooth, so that polishing can be faster and better.

When scraping putty, the pit can be filled in several times, first and then gradually. The first grinding must be done horizontally with the coarsest sandpaper, and more water is needed. This is usually flat. Then, if there is a small pit, fill it with putty and polish it with coarse sandpaper. Until the whole surface is flat, there is only a sandpaper path. Then scrape the putty, this time the putty must be very thin, and then polish it with sandpaper that you think is suitable.

There are two ways to scrape putty: full scraping and alternating soft and hard scraping, in which full scraping is divided into filling scraping and relying scraping; Soft and hard alternate scraping method can be divided into "first scraping" and "belt scraping".

The purpose of scraping is to fill the surface depression of the component with thick putty in several times. When charging and scraping, the elastic part at the upper part of the mouth of the hard scraper is mainly used to match the strength of the hand. The consistency of putty used in scraping coating is slightly lower, which is used for the last and second scraping coating to make the putty on the surface of the component smooth. When scraping, the upper part of the scraping mouth is mainly played by a hard scraper, and the putty is scraped to make it thin and bright.
