Looks like varnish to me. I have a gallon can of "Methylene Chloride Free" paint stripper that I've used for all of the ones I've repaired. Works great, but you must be careful to keep it only on the circuit side of the board. I then rinse off the board under running water using a small scrub brush then blow dry.
