I've used Final Inspection and Quikshine and prefer Quikshine enough that I'm willing to pay about double the price I can buy Final Inspection for.
I haven't tried Final Detail though. I'm going to pick some up the next time I go to my Meguiars distributer and check it out because I've heard good things about it.
Wax Shop's Slick Stuff is also a good QD but it is increasingly hard to find.
wax shop slick stuff, i used to see that at pep boys in the beige bottle, wow havent seen that stuff around in a long time
that clear kote stuff is top dollar, i have used final detail and real impressed with the results, if someone actually can say clearkote tops that ill try it cause FD is top notch stuff
Well I do have both Quickshine and Final detail and use both. I'm down to about a 3rd of QS 32.oz bottle and still plenty of FD in gallon form. To me, QS still has little more of a slicker, smoother feel to it and I can use on windows to repel the rain. I tries FD on windows but I kept getting streaks. I know someone else commented that they no problems with it on glass, so I'll keep trying it.
But FD leaves my car with alot more of a glossy sheen to it. The first time I used it was before I went to work that afternoon and coworkers commented how much "newer" my car looked. So I'll stick with the FD for awhile. Also if you're into the "smell" of products, FD beats QS hands down. :up
