Trying to give my WRX a good shine up before the summer, and found that I've got some SERIOUSLY baked on waterspots on the hood... generous application of vinegar and clay bar don't budge them, so I think I need to do some real paint cleaning. I picked up the Fine Cut cleaner but noticed it says ONLY FOR USE WITH ROTARY BUFFERS... now I have a little 6" cheap random orbital polisher but I know that's not the same thing... but it seems from the stickies that you allow for hand application of all these recommended products. Will I be able to hand-buff my problems away? Should I try my random orbital or will that make things worse? I plan on going from the #2 Fine Cut to the #7 Show Car glaze and finish off with S100 over the top. Seem reasonable?
