Yup, that's the question, please feel free to suggest other products. Give me a whole list because I've tried a good number of LSP's/aio products, and I feel that Klasse AIO still produces the slickest surface after being fully cured. I've tried P21S, Optimum Spray Wax, PS, OS, RMG, Natty's Paste Wax, Eagle One, Collinite 476S, etc (I've never tried Zaino yet though)...I will say that FMJ was very close to producing the same slickness as Klasse AIO, but still not quiet as good. I really don't care about long-term slickness, rather, just the slickness produced minutes or hours after a detail. Every time I use Klasse AIO, I get the most amazed reactions from customers. Please suggest any product, aio, lsp, etc... that you feel produces a rediculously slick finish.
