I just bought some used p30's from a friend to put in my ITR block that Im rebuilding. They're pretty dirty right now but they're still in great condition. I was going to have them beadblasted and then I was gonna polish them and make em reallllllly shiny. But I was wondering if beadblasting was really necessary or if I could get them looking just as good w/ out it?

 

no do not beanblast/sandblast them.... just do what your doing on your previous post... but man i use just a wheel brush almost like a brillo pad and a rag with carb cleaner to clean the dome up... easier, F all that dremel crap...
