So I just bought a Dremel its a Ryobi one if that makes any difference. 
  
Has anyone had any experience with polishing up their cam covers using a Dremel? 
  
I'm not removing anything just doing it in situ as and when I get some time. 
  
I need an idiots guide please, how to do it, accessories to use ect. 
  
Anyone please! Lol
