nice revue; agree with all. the collinites are fine products
personally, i have switched over to the collinites ( used to use #16; still like it and use it but have leaned towards the collinites) for my winter wax for those harsh ny/penn winters. i use the 845 followed by the 476 ( some use 476 followed by 845 claiming one gives a wetter look. maybe ? haven't really considered it. at most i would think the differences are negligible) about late october/early november put on by machine after a good wash,clay,and polish. get all winter out of them, usually lasting until march or even april. that is some durability. unless i get one of those "balmy" winter days of mid to high 50s in january /february, i leave the cars alone and don't wash them. hasn't hurt them a bit and they look fantastic again after a full detail in the spring.
only criticism of the collinites is it smells like dung but judging from how they work, i guess i'm going to have to deal with that.
