Should be polish first then LP. LP is a wax pre-cleanser, it removes any stuff left before waxing, thus should be used after polish Also if the car is already swirl free, no need to polish, just use LP.

*You don't win a prize, and I knew there was something about that list that didn't look correct when I wrote it! Cheers mate, will correct it now.
