I use:
- Megs GC because....Cheap, good lubricity, does a good job of cleaning and rinses off well. Oh....and it can be found locally! Big plus.
- Zaino Z7 because....It was supposed to work best with Zaino sealants, to be honest I don't find it any better than the Megs GC, and I probably won't re-order it when my current bottle runs out. Presently, I only use on my Zaino'd S2000 so it should last me awhile.
- ONR because....I live in New England, and my outside water source and hose are shut off and put away during the winter months. This winter was my first experience with it and I really LIKE it. So much so, that I think I may continue using this as my shampoo of choice all year long. If you're looking for more info on this product, just run a search. There's not much I can add to what's already been said....other than I can be counted on as another person who was at first skeptical and has now seen the light of this outstanding product.
Oh yeah...If I ever feel the need to strip whatevers on the finish to prep it for something new. I use Klasse AIO. No more Dawn washes for me.
