I had the Lifeshine treatment a few cars ago on a Captur, and to be honest it did no better job than when I washed the car using the Autoglym shampoo. Renault use it, and like I was offered it with the Jazz I always turned it down. Renault gave me the kit, which I still have. I wash generally once a month, and use the Aqua wax every three. It is all good product and the beading is excellent, making washing easy, but I always rinse using hot water and dry using a micro cloth (that should be in your kit)... but I felt the Lifeshine offered by the garage was a bit of a con.
