Just bought a spray can of minwax polyurathane for my final coat on an old walnut table. Previous coats had been minwax polyurathane fast drying rub-on with sanding in between. I live in a arid region of the country, so I know moisture is not a problem. The spray can of minwax left a milky, rough finish. I will sand it off tomorrow and go back to my hand rub routine. Very disappointing product and waste of money!
