<html> Since you are wet sanding (which I don't recommend on sealer), my guess is that you are not allowing sufficient time to lapse for the water to evaporate out of the pores before spraying again. Or this in combination with the other technique possibilities mentioned. The micro pores are a source of aggravation, even paste wood filler does not fill these pin-holes.
