Obsessive.
Green section has final finish paint. Next will be striping.
In above photo, joining section (bottom 2cm) is not exposed as it is a joiner and is coarse.The following picture is the second coat of white. If you notice it has standard paint look. That's why it is wet sanded between each coat as those imperfections (bumps) magnify with each coat. The final 2000 grit removes all appearance of the bumps and then it is up to the polishing to make a reflective finish.
The grid pattern is just the sun passing through our screen on the patio, making a stencil grid pattern on the white.
