For those of us that are not OCD about car detailing with the most expensive waxes, clay bars etc, this is excellent stuff. I have used it for several years after it won awards in AutoExpress.I have just collected mine at Wakefield and it still shows available at several branches.
What I like is the ease and speed of application, it can be applied in direct sunlight and it leaves no deposit on your plastic/vinyl trim. Beads water off for ages.
Full RRP is a bit high as quoted at £18 as it generally can be bought on E-bay around £11 or £12.
I also ordered and collected the Armorall Shield for alloys at £3, which is a brake dust/dirt repellent and again easy to apply. http://www.halfords.com/motoring/car-cleaning/wheel-tyre-cleaning/armor-all-shield-for-wheels
