I just bought an ST 202 in London, but I live in Scotland where cars dissolve quickly, so for me it’s a must have. Yes, it’s costing me £600, but what’s the alternative? The car is immaculate underneath and I want it to stay that way. I am using a company called preserve protect preserveprotect.co.uk who have the car just now. Great reviews and they use Dinitrol. They will update me with piccies and I will try and post them. I know it’s in Scotland, which is no use to you, but have a look at the website and make your own mind up. Hope that helps you. Iain.
