Zinsser's new Bulls Eye brand sealer is a 2-lb. cut of pure, clear, dewaxed shellac -- so of course it's imbued with more than a little magic. Dewaxed shellac is an ideal sanding sealer. It bonds tenaciously to virtually any bare wood or finished surface; it dries very quickly, sands smooth with the greatest of ease, and since it contains no stearates it provides a reliable base for any kind of finish going on top. Thinned with denatured alcohol (3 parts alcohol to 2 parts sealer), SealCoat works as an excellent pre-stain surface conditioner, reducing blotchiness and uneven penetration of pigment stains.
