Welcome Bruce! Nice R bike you have there, it's a beauty. I can see the areas needing touch up in the photos: if you want a little container of Red basecoat to help give you a start point for matching, shoot me and email and we can work out the details on shipping you a free sample. I have several versions of Ducati red color matches that I have had formulated over the years, and like you mentioned, it is always a challenege to get the right shade Red.
