When using products like Klasse AIO and SG application/removal is a snap. I've never timed myself, but I think I can have the car done in about 30 minutes when applying/removing either the AIO and SG. As far as claying goes, well its a bit more involved, usually about 45 minutes or so. My car isn't driven everyday unless the weather permits it, so I'm sure thats a factor as well.
