You asked for methods of work, so I'll share mine. After sanding, both epoxy and varnish coats, I use denatured alcohol and paper towels to wipe down my boats. It is simple and quick drying and leaves no residue that I can detect. I've found when wiping down with water, I can almost always go back over the surface with the denatured alcohol and pull more dust off of the surface.

With the epoxy coats, I do very little sanding. I prefer to use a card scraper.

With the varnish coats, I wet sand between coats with 400 grit. On my new boats I coat with about 7 layers of varnish. I typically re-varnish every other year with two or three coats. Once I start seeing the old shine again I just can't help myself.
