You can buy Autoglym in almost every town and city in the UK and it will give good results or you could order Carlack and it will give good results. The difference between Autoglym, Carlack, Zaino etc is not huge but is mostly down to personal preference. I am not keen on Autoglym shampoo, fast glass or interior polish but this does not mean they are poor products, it is simply my preference

If you want to know more about these products and their strengths and weakness, have a look at the Detailing World forums.

To answer your question, I would be happy to use Autoglym or Carlack, Klasse is more expensive and is the 'old' formula but if you could find a cheap suppler it would still give good results
