Totally disagree.if its done properly as mine is then cleaning is totally effortless.and youre not meant to polish the car after or it will destroy it.anyone can apply it by buying both stages on e bay. A bottle of each stage is peanuts on there.5-8 quid for both in some cases.i agree the 200 is a rip off but youre paying like 90 quid an hour garage labour costs.get a nice dry mild day, 2 hours of your own time and the benefits are worth it I think.unless you have an older car then polish yes.new car with diamondbite.pointless but up to you really
