Well, it depends how ambitious I get... At a minimum I want to polish the valve covers on the front head (including the oil cooler bracket), and the cam covers on both heads. I also want to finish polishing my chain gaurd (Ducati part, started as brushed aluminum, I got it about halfway polished right now by hand). What I ultimately want to do is have the engine covers polished as well. Not too hard to do myself I guess with the right tools, but it just sems easier to drop it off somehwere and pick up a pile of shiny stuff later. The hardest part about polishing the painted stuff is that under that nice paint job is a really rough metal surface. I did the front valve cover by hand already and it took forever to get all the bumps out. It's still not perfect, but looks OK. Probably a bit easier with a couple power tools involved....but I would be afraid of messing up the mating surfaces of the part and ending up with poor fitting.
I'm usually a DIY'er due to the personal satisfaction and monitary reasons, so not sure exactly why i'm so hung up on finding a shop. I do have some part ideas that I may want to get quantities made up for sale that would need to be polished.
