I'm trying to shrink with just water , misted on, and seal with a waterbased poly. I but 3 coats of diluted poly on wood, dampen silkspan, poly around perimeter. After poly dries I mist with water, very lightly, dries taut. then seal with 3 more coats of poly diluted with alchohol. So far it seems to work well. Not looking for concours finish just a non-smell finish. John
