David, Michael and all:

Ii made the same experience with powdercoating. One looses the detailing, coating is much too thick and also the finish and depth of a typical varnish or laquer can not be achieved.

With an old swiss racer, an Itca bicycle, a made some bad experiences , giving it to a car painter -expensive and! sleazy job. For the restauration of a very old and sprayed over Cinelli, Model B finally I found a very reasonable and painstaking painter ( 90 Euros for an exquisit paintjob) here in Berlin with a professional paintbooth and a 80 degrees Celsius dry kiln. His company is concentrating on industrial units like framework for furniture, technical housings, lampshades -everything were powder would be inappropriate for technical or design reasons. He explained, that it is not even necessary to blast and then e.g. rechrome the frame. If one sands off the existing paint thouroughly down to the old primer or the original paint with 180 sandpaper (wet) by hand or carefully with a machine, the advantage would be, that remainig solid old paint interconnects very firm with the new one, providing, new and old paint are chemically related. E.g. pyroxylin based varnishes were often used still in the 70ties, conditionally it is possible to use synthetic resin paint on the old ground (test it on a spot). Obviously no acrylic paints!!!. A professional painter should know. So find a paintshop, which is concentrating on industrial units. I heard that -for some unknown reason, propellers for airhandling systems are often spraypainted and not powdercoated. Not sandblasing means, one preserves as much of the original substance of the frame as possible. To me, a well done paintjob looks

always more authentic than powdercoating.r Good luck!! Kind Regards,

Benjamin Köhrich
