I detailed a Focus ST in black a few weeks ago after explaining to the owner why auto car washes and £5 kurdish car washes are no good as all they do is spread grit off other peoples cars all over your car then blast it off with a jetwash, use acid that strip the lacquer off the wheels eventually etc.

When i got the car to me i spent 6 hours on it, tardis de tarred the bottom half, iron Xd the alloys, then machined it with a finishing pad and some megs 205, followed by 2 coats of poorboys wax, it looked brand new then three weeks later he put it through Asdas auto car wash, back to stage one again. I don't get some people, it takes 5 minutes with a couple of buckets and some water, if its a old runabout fair enough but i don't understand people who pay 5 grand upwards for a half decent motor then treat it like that when it comes to cleaning, its like buying a new pair of £100 trainers then digging your garden the following weekend in them.. some people !
