I'm not a car detailing nut, but I do keep my machine far better than the average Joe does.
On the recommendation of a friend who runs a used car lot I got some Concept Vista trim restore, 10 quid for a 500ml bottle. He reckons its as good as Polytrol on car plastics, but half the price. Anyhoo, it arrived today, and as the sun was making a rare appearance I decided to give it a go on the bumper aprons and arch tims on my XC90.
Wow! Thats all I can say. I'm told 2 or 3 applications a year is all that is required. It's very easy to apply, so if it lasts as well as it looks I'll be extremely happy,
