Q: I just bought a house and the previous owner never cleaned the oil off the cabinet doors near the cook top. I had the grease cleaned off but the finish appears etched, like you can still see the drip marks and spots. Is it possible to put glaze over a satin poly finish without [...]

Tuesday, September 22nd, 2009

Q: Which is a more durable finish for a dining room table, Varathane or lacquer? A: Varathane is a brand, not a type of finish, but the company is widely known for their polyurethanes, so I will assume that is what you meant to ask.

Brand Name Winners
