Another
for Griot's from me.
They have great customer service as well.
My only complaint is that the Best in Show wax is FREAKIN' HARD to remove. It also leaves white marks on black plastic/rubber. I think I got spoiled by synthetics like Zaino/Wolfgang.
If I really want it to shine (maybe once a year) then I'll use their clay system, the random orbit buffer with their machine polish, then I'll put a layer of synthetic wax on. After that it's much easier to use the Griot's Best in Show wax.
