It's not ink but rather it's a type of paint . It takes three days for it to dry on the new ID plates . Since this is my first time doing this type of thing I guess time will tell . By the way, all of my cub is powdercoated except for the instument column, the engine block and the transmission case . I also have to paint the gas tank as it's sections are soldered together and would fall apart during the 400 degree baking part of powdercoating . I thought about taking the sections apart, removing all traces of solder and silversoldering the sections back together . Then it would tolerate the baking temps . Not quite there yet though . I think possibly warping the tank sections would have to be overcome first due to the silversolder requiring higher temperatures over the softer lead solder . This stuff just keeps me thinking all the time and I love it . At 67 years old I gotta keep on going and these Cubs are just the ticket ! Oh, I almost forget, the silkscreeners have a very strong cleaning solution they use just prior to printing . That should help the paint to stay inplace . My next project is a Cadet 124 and I plan to powdercoat more pieces on it . That will require more dissassembly and more work . Oh well, it never ends does it ?
