I use collinite, but you might try klasse SG over the AIO as it's supposed to a better job at repelling dirt while lasting as long or even longer than the 845.
Only thing is SG sort of a pain to apply and you can't f-up I heard. Collonite on the other hand I could apply every month or something and it's easy to do so.
