I have used Z6 and like it. What are your guys thoughts on some other QDs out there? I have not tired to many just wondered what other people like and use. I mostly use sealants(zaino) and top with nuba every now and then.
Z6 is expensive (up here anyhow) so I just grab the cheapest stuff at Walmart, which is the Mother's California Gold Showtime stuff. A big bottle of that stuff is only about $6 or $7 and lasts me months and months. It looks just as good as Z6 to me, at half the price.
clearkote quickshine leaves a very slick surface. works good on windows too. i think it's around 30bucks for a gallon. i use it pretty frequently on my black car so i get it by the gallon.
I'm a big fan of Adam's QD. You can use it on just about anything on the exterior of the car. Works really well on windows as well and almost mimics rain-x. On darker cars, I like Prima Hydro. This is probably more of a spray wax. You have to be quick with it though as you don't want it to dry up on you. I picked up some Aquawax today at Carquest and will give it a whirl shortly.
I'm using FK425 for interior wipe down, glass and any issues on the exterior. It became my goto in a pinch and I'm hooked again. I wonder what got me sidetracked???
