Hmm, not too sure about the 3-4 coats the article mentions. The radiator guys I dealt with [albeit on 'moderns'] blew a well thinned single coat of paint over the core. Never made a note of the product, and it was probably proprietary, but it smelt as if it had a very high VOC content, certainly it dried very quickly and looked to have good coverage. Maybe ask your local radiator repairer?
