Patinais a similar coat that forms on other metals such as copper or bronze, but the term is also used to refer to rust. ![]() Especially after I showed her examples of exceptional paint covering exceptional fillets. Rust is nothing but an outer coat of oxidized iron that forms when steel or cast iron is exposed to moisture and air. While Lauren was initially a bit bummed that her pretty, raw frame would be covered with paint, after explaining this, she understood. The best thing for an immaculately-finished fillet frame is a great coat of paint. Or watch the light reflect off the paint as it coats the shorelines. Simply rub your finger over a fine fillet braze to feel the difference. It makes their job easier and the paintwork shows.

I’ve heard just about every frame builder complain about the double-edged sword that is fine fillet brazing. We’ll use this photo from Tomii Cycles as an example, only because it’s the most recent, clean fillet photo I’ve seen on my Flickr feed. What came next was a very simple conversation that many frame builders have with their clients on why this isn’t a good idea. This is what came out of Lauren’s mouth when I showed her photos of her Icarus Porteur. So pretty! Can’t we just put a clear coat on it?” Photo by Nao Tomii Can you Clear Coat Raw Metal? ![]()
