There are several steps to spray the meter.

The following steps can be adopted for construction: 1. Sand the base surface to be brushed with sandpaper to remove surface burrs; 2. Use oily putty to scrape it flat in thin batches, and then use sandpaper to polish it again after drying (usually 2-4 hours in spring and summer); 3. If your wooden base is not particularly smooth, please repeat the second step; 4. If possible, spray primer twice; If you can't spray, brush, and generally choose primer. 5. Brush with colored topcoat. In order to achieve good results, I suggest you spray it. If there are no conditions, the surface leveling effect of brush coating is not as good as that of spray coating. The top coat is usually twice, and there is no need to polish it in the middle. It should be pointed out that if there is no experience in scraping putty and painting, the effect may not reach the expected effect. If you want to achieve good results, you still need to ask professionals for help.
