Looking for cover plates for a 1988 Thermasol Whirlpool Tub, i.e. six - 2 piece jets, 2 air intake controls and the suction cover. Thermasol no longer makes these parts and I have not been successful with metal refinishers. I am not in a position to install a new tub which would require a complete bathroom remodeling - this one works fine. Any leads and/or alternatives would be greatly appreciated.
