I bought a used yellow Maravia Williwaw 2 and it has some pretty atrocious rub marks. I used some Simple Green, some MEK, and some elbow grease and cleaned it up a bit but far from perfect. Trying to minimize in the future I decided to spray paint and put many coats of enamel to harden and keep from marking. Just had another thought and need your opinion. What about wrapping the entire frame in electrical tape? Tightly wrapped and in color. Started a small section and it looks pretty good (no use so far though). Has anyone done something similar, even if it were a maintenance task doesn't take much time or money.
