VeeFer97 is right about applying the patch right. In my garage many people choose to go with a patch on their cars insted of buying a new tire. You have to buff the inside tire smooth, sand paper should work, and after putting on the glue and patch you must use that roller thing he talked about. One a bike i really wouldnt recommend a patch, just because they are dangerous enough, but if you are going to patch, do it the right way.
