I do not claim to be an expert here but when I see a good old classic or antique bicycle that has the imron wet look it drives me crazy. I understand that a restoration may leave you no choice but to clear coat with imron makes me shiver. My preference (not that it means anything) is to take a salvageable finish and clean, wax and polish it till my wrist hurts and continue to maintain it. Time will claim everything sooner or later but I can't imagine museums puting imron on everything they wanted to protect. Imagine the Mona Lisa with an imron clear coat, <<<there goes that shiver again.>>>
