Thought I would throw this out; A lot of people do not know how to properly sand. With the grain is a given but how much to you sand ? One rule of thumb I use is to make 7 passes over one area and move on. & passes gives me the smoothness I need for the next coat. With each grit I practice this and always can rely on the proper smoothness is achieved.
I dream a lot. I do more painting when I'm not painting. It's in the subconscious.
