I stripped the finish from an oak desk with Formby’s, waited 7 days, then wiped on 2 coats of oil stain, followed by 4 coats of Waterlox, over 6 days.  There were no drying issues with any of the coats.  It’s now been 7 days since the last topcoat, and the finish looks and feels good.  How long should I wait before putting the piece into use?  I will be placing a computer on the top.  Thanks.  John
