Finish repelled in spots

Q: I had my hardwood sanded and refinished and high-gloss put on. It had little round spots all over it that the polyurethane did not cover. So I had it buffed and recoated with the polyurethane and still the spots are popping up everywhere, where the polyurethane did not stick. They tell me that there’s nothing they can do for this. What is causing this?

A: There has got to be a contaminant which is repelling the finish in those spots. Poloplaz has a strong cleaner which can remove contaminants. It is called Tie Tac and I’ve used this on more than one job. Using it rescued the floor.
