Well i like it, but i haven't tryed anything else, so my opinion might not matter too much to you. I feel that application was fairly easy, SG required a little effort to buff out, but other than that i feel that it's a really good product. I also think it makes my car look amazing!
I've read a lot of the theads and people seem to like it. I'm looking for something to use on my Z71 Tahoe which stays outside all the time. Need good protection and an incredible shine. ZRight now I'm using Griots polish and Best of Show. I have a black garage queen that I only use Souvern on.
I am a klasse user. It takes a little forethought to use Klasse. If you decide to use Klasse then do a search for the jimwh method.
One reason I like Klasse is AIO. AIO can save you two steps. It saves you one step if you Mother's clay then you do not have to do a second wash before using AIO. AIO stands for All-In-One, which means it both cleans and seals. This saves you from using a paint cleaner and then a sealer.
The second reason I like Klasse is durability.
There is a down side: no technical support, a hazing problem that may occur.
The shine is very good but, other products can give a great shine.
I think thecarguy was right on. I haven't tried Zaino yet, but I am happy with the results I have with Klasse (Blitz). When I compare my freshly washed car with that of my neighbors or with others on the road I feel good about the results. I don't know if it is the best or not, but I know you won't be disappointed with the product itself. I am however intrigued by Finish First and the pics I have seen posted recently.
I love Klasse. I won't say that its better or worse than anything else but if you are looking for a product that is easy to use, looks great, lasts a long time, and protects your car then you can't go wrong with Klasse. Its really great stuff. Zero complaints about it from me.
I'm a first time Klasse user and it's great! Like they say, a little goes a long way. I had no problems buffing the SG off. Topped with Souveran was awesome.... =)
I like it, it fills and hides swirls and light scratches like nothing I've ever seen. It is a bit of a learning curve when applying so you dont put too much on. The shine is bright and "clean" looking. After about 5 coats of SG I topped with Blitz Carnuba wax and it looks awsome.
I found it easy to use and easy to care for afterwards. You can find my instructions here until they get moved again or posted in a more permanent place.
If you can't find them, just PM me and I can send them to you that way.
