I'm just curious what QD those of us who still cherish a good ole pure carnauba like to use after washing to renew gloss, slickness, etc.
Number one for me is probably Griot's Speed Shine. I love the heck out of it. It has never streaked for me (although I never QD under direct sun), it wipes clean right away, has no alcohol content, smells AWESOME (this is a big deal to me, as much time as I spend QDing), and is pretty slick. It's also pretty thick for a QD so I feel safe using it on moderately dusty surfaces. The actual carnauba content is pretty low, as in < 1%, but I still wouldn't use it between layers of sealant. It adds a LITTLE shine, but mostly I feel it doesn't take away, or add anything, to the finish, except for making it clean again. I like to let my LSP do the shining.
Number two is Sonus Carnauba Spritz. It's equally as easy to use as Speed Shine, but I go through a 16 ounce bottle of QD so fast my head spins, so it's not really cost effective for me to keep this on the shelf, AHEM DAVID
It has the same grade of carnauba as P21S/S100 and is very user friendly, slick, etc. All the good stuff, just too small of a bottle.
I love Pinnacle CM, but I consider that more of a spray wax than a QD. One Grand Show Off is awesome, but can be a little hard to work with. EFCP was nice, but a little thin in consistency for my likings.
