I polished my throttle body, fuel lines and other stuff myself w/ the polishing wheel on the aircompressor. Took off the Throttle body, did all the lines and fittings in the engine. Used the brown bar polishing compound. Dont remember what it was called but it worked like a champ!!!!!! It wuz not hard to do at all!!!!!!! VERY little effort. The main prob. was making sure I didn't hit the metal w/ the metal edge of the wheel and scratching whatever I was polishing. TOOO much effort to do it by hand!!!!!! Just make sure you have different sized wheels and cones to get into tight spots!
Also, be sure to lay towels over the rest of your engine if your working it it, if you use the polisher. I flung SH** everywhere and it was a PITA to clean up...Also watch for flinging SH** on your hood blanket!!!!
Theres pics of my engine in the BOL on "Got My Chromed Radiator Hoses on Today!" If you wanna see it.....
Good luck!!!!
