Cheers never would have thought of scewfix and 34 a bottle would suit my friend as he's very careful with his money
I've used various waxes and find the price: performance of turtlewax original hard to beat (just don't get it on rubber window trim). Not the in vogue brand but for £4 a bottle (Homebase) you can't go wrong. Screwfix stock a surprising amount of car cleaning products at good prices too.
As above, is it truly a wax he is after ? I like collinite for mine but you really need to clean and polish it first
Best of washing, polishing then waxing as this would protect it better.
As my above post, buy too cheap and it will just wash off after a short period. Bilt hamber double speed wax is very good without costing you a zillions
