Had to get the radiator power coated as the paint on it was starting to peel off, I forgot to take the Chrome valve parts that screws into the radiator off, I just got it back and and the guy powder coated everything, I tried to remove the powder coating with paint stripper but it have taken all the chrome finishing off so can I buy the replacement part that screws into the radiator or will I have to buy two new valves? {This valve part should be chrome not white.}
