Many products claim to be ‘professional quality’, but this stuff really is as it’s used by Aquanought’s valeters. And you can soon see why the liquid’s such a favourite when you use it, as the solution works a treat. Simply spray, wipe, then buff to a water-repellent shine. There’s no hard work involved, and the compound can even be applied to the vehicle’s tyres, wheels and interior. The biggest drawback with ProKote, however, is its price. You get only 472ml per container, which is good for a mere five or six washes.
