Over heating -- followup and question

[Rob Robinson]

Leroy I too cleaned my radiator recently and did the best I could without
taking the thing out. I noticed some paint had flaked off but opted not to
repaint because even though I cleaned it out as best I could I am not
confident that it is clean enough to paint. I'd be worried the paint would
combine with any dirt/soap residue left behind and clog the fins up.
