I know'a'noothing see
I've had my wife's micra done twice for £20 a pop for an hours "wax" and to be honest i was disapointed at how crap it was.
I poped in to a place down the road that quoted me £20 for my Audi which would take an hour to do using Auto Glym.
Soo.. would the results be just as poor? I really don't know and have never atempted using "clay" or any other detailing products on my car. I'm happy to spend some time but not hours and ours, and equally if for £20 i'm going to get a average wax it's not worth it either.
Advice please if you would. Esp you detailer pro's out there
