Hope your business is coming along ok.
I would stick with the better brands as these have proven themselves time and time again.
The likes of Klasse, P21s, Poorboys, Wolfgang, Clearkote, Sonus and Meguiars etc.
Autoglym is not a bad product, I just feel personally it tries to do too much for one product. I could not use it on a customers car, knowing they will come back and say that the swirls have majically re-appeared, when all I done was mask them for a short time.
You need any help don't think twice about emailing me etc.
John.
