Hey TBB,
Let me clear up a couple of things.
I myself never had contact with Bob from klasse. It was another member of the forum way back when. All Bob recommended was the wipe on wipe off approach to using SG. Back then he never said anything about cure time. He only mentioned that recently in his interview with CMA. The 24 hour/ 1 week cure time was recommended by Ron Ketcham. He is a chemist and used to be a member of this board. He's also held in high esteem by many of us who had the chance to interact with him.
The problem with klasse is that they offer too much conflicting information about thier own products. 2 years ago Bob said to wipe on and off SG, now in his CMA interview he tells ppl to leave it on for 24 hrs before buffing off. You see why us long time klasse users shake our heads when klasse opens it's mouth.
I personally adhere to the 1 week wait time. I just throw on a coat after my weekly wash. I also use the WOO technique as I've found it to provide the exact same results as the other app/rem methods. My car still looks and feels fantastic even after a brutal Toronto winter. It's the easiest and most convenient way I've found. And the results speak for themselves.
