The detailer spray may be your problem. I have used Klasse for years and never had a problem....but I immediately use the SG after the AIO. Start over with a good wash, AIO and then SG. Multiple coats of the SG will bring out the finish you desire.

And use both products very sparingly.....if you can barely see it, you are using just enough. And use water on you applicator instead of the detailer and I think you will be much more satisfied with the outcome. Good luck and you will see that the effort is worth it.
