Hello guys, I bought something like this a year ago:http://www.ebay.de/…/290885017632?… But never used before. These are loud hoods, unfortunately there is nowhere to be taken for what. You have to stick away everything possible, roof rails, plastic parts etc. Do you only polish large and easily accessible surfaces with the excenter or really everything? Are there many places where you can only go badly….!? I have from Meguires the step 1-3. I should only use that with the hand or? What should I use with the excenter best? Have a BMW in sparkling graphite metallic. Lacquer is in good condition, never polished. You can see just in direct sun these streaks from the washing system. Would be very grateful for some advice! Greetings Felix
