I've read on the interwebs that if you apply Klasse SG and let it sit for 20 minutes to an hour so that it can dry, and then you can let it cure overnight without buffing off the residue. This way, you can buff off the residue the next day and immediately apply the next coat. This also allows you to spritz some water or a quick detailer to ease buffing SG off since it is kind of finicky during removal.
I didn't use this method but I did apply two coats of Klasse AIO and two coats of Klasse SG to the G35, and I applied a coat of Dodo Juice Blue Velvet to the hood. The car definitely looks great but I can see how some people wouldn't like the look of the Klasse "Twins" on a Black vehicle. I have to say, both Klasse products are terrible to buff off. If I don't buff off AIO immediately after applying it to each panel, then it becomes very difficult to buff off the residue. Sealant Glaze bonds very tightly and leaves lots of hazing and streaking and required a full wipe-down with a quick detailer and a few towels after buffing it off with my Porter Cable and microfiber bonnets.
