Honest never, on my kids lives. I have never owned a track bike before and i would never attempt to spray my road bikes, as they have all been virtually new amyway. I am pleased with it, its turned out better than i thought. What you cant see is though there are lot of little marks here and there and the paint isnt very good in areas just the pics don't show this up, but as its only for a track bike im not bothered.Holy shit mate Own up, you done this before. you must have done.
