I discussed this topic with a local painter and he said he can blend kandies. Well after listening to him explain for 30 minutes on how he would go about doing the job & all the hours it would take to achieve an unnoticable blend, I said it would be quicker and easier to redo the job. On a large area of a car maybe blending with an airbrush, might be worth the effort, but on bike parts, redo is the way to go. Unless you can cover with a graphic/flames etc.
