I've been trying a few different ones the last year. I have about 6 total.
I think the 2 best ones I have ever used are
Meguire's
Final Inspection 34 &
FK1 425 Slick Poly Wipe.
I have the
Wolfgang and the Optimum as well.
Wolfgang isn't great and Optimum is ok, but I don't think it holds a
candle to the 1st 2 I mentioned. My cars always come out flawless with them.
