   You might have some adhesion problems with a oil over this finish. But as it has this finish already, here goes. Sand with 220, we use Sherwin Williams vinyl sealer over waterbourne with good results,and then either a varnish or Kemvar on top, as its waterresistant and durable.

   *Polycrylic is a water based acrylic/urethane, not an oil. Many water based products are not designed to work well over paint. Please go herehttp://www.minwax.com/produse/clear/pucfpc1.htmCheck the can and the instructions again.You should go with a system designed to work together -- or the paint itself may be plenty durable.

   *Adhesion is not a problem with the coating. The Polycrylic finish was great - shiny and hard (when dry). Leaving drops of water or even a wet cloth started to dissolve the finish. I called up Minwax's help line and they said that cure time was between 5-7 days. It has been that long! Well, I scuffed the countertop with 220 sandpaper. Now, I'm searching for the next step... another water-based poly or more water-based hi-gloss enamel followed by a different protective coating.

   What is the sink made of? I have an enamel sink with the same problem, it needs refinnishing. I haven't done anything to it yet. Should I go with oil based instead of water based polyeurothane of some sort. How do you apply what you are using?

   I am using a Shrwin Wms NON-urethane wood varnish over enamels

   I painted a bathroom sink countertop with a water-based hi-gloss enamel. I have applied Minwax's Polycrylic Protective Finish, a water-based finish, that the manufacturer states, "... resists damage from abrasion, scuffing, chipping, water, alcohol and other common household chemicals." I have allowed this finish to cure for over a week. When a water is left on the surface for 5 minutes, it "melts" the polyurethane! I would like to put on a durable, non-yellowing protective finish that will hold up in this wet environment. Any recommendations are appreciated.
