Fisheyes are common in colder weather but for it to be beading up is not a good sign. Someone may have used an endust type product on it which will make any finish you put on it fisheye. Have you tried a good stripper coat or washed it with spirits? I have had this problem and it took many very thin coats of lacquer to build up enough finish that it would not pucker or "Orange peel"

If it is a silicon contamination I dont think there will be a fix.
