Yeah I’ve learned a long time ago to do several sand patterns with the screen sanders.Been using one of those for nearly 30 years. Awesome tool. Be careful to limit the suction pressure to just what is needed (behind the handle) and don't sand perfectly straight with the grid/grain of the sanding screen or it will groove the finish.
I also use coarse to start and fine to finish then I go over it with a Sheetrock sanding sponge.
Amazing the imperfections you find once you hit it with a damp sponge.
