AudiPartner Posted July 12, 2016 Report Share Posted July 12, 2016 I'm not necessarily interested in anything the dealer has to offer, but I wonder if any of these glaze treatments are worth doing? Or is it better to stick with traditional car care? I've seen some great pics of cars that have been treated with Gtechniq Crystal Serum and it looks awesome. But is it actually any good/worth it?
