I have not tried that many waxes and/or sealants. Over the last 14 years I have gone through a bunch. For sealants, I have tried Klasse AIO, Zaino, Zaino CS, Mother's Reflection, Meguire's Gold Class, Meguire's ColorX, Menzerna FMJ, BFWD and Optimum Spray Wax. As for waxes, I have tried Mother's, Mother's Cleaner Wax and Autoglym HD.
For sealants, BFWD is my favorite followed by OCW.
For waxes, Autoglym HD wins.
