After 6 coats of 1k PU Rattlecan clear I have sanded back with 400g. I have two different texture as u see in pictures
1. Somewhat smooth uniformly white smooth kind of texture ( Marked as 1 in picture)
2. Other areas which are with shiny spots ( Marked as 2 in picture)
Does that mean I have level sanded in areas marked as 1 and the areas in 2 are high and low spots and is not yet level?
If so what can I do to level those areas?. Should i keep spraying enough coats so that it becomes thick enough that i can keep sanding aggressively to achieve a level as in 1?
Should i keep using the 400g for this? At what point I should go for finer grits?
