Yep i have to agree the bucket and the grit gaurd is a must, or using a 2 bucket system 1 for was and 1 for rinse , no point is paint correction , polishing and waxing , if u going to introduce more swirls the next time you wash. Chatting to allot of people i notice many overlook the washing aspect , and this is the most important. I simply love the Caddy system :-) makes for a good mobile stool when working with a machine on the car .. and prevent sore back after a detail. Awesome tool !
