Good choice for block sanding
Creates a dense surface for the sanding block and does not clog the sandpaper. Makes a high pitch sound against the paper that drops as soon as the sandpaper is dull. Dries fast and spraying it wet is a bit difficult. I ended up mixing in 1 part extra slow reducer so I would have more time to spray. I would never try to use this as a sealer due to its extremely quick set up time. I can't comment on shrink back, but I am going to give it a week to sit before blocking for the second time.
