A few months ago I put together
this list of "best" waxes and sealants. I have tried a few of them over the past two years. Sometimes I think I can see a difference; sometimes I'm sure I cannot see a difference. I don't know. It's all very subjective. I do know that my black car looks great in every wax and sealant I have put on it, and it looks better after it's been polished. I agree with those who insist that proper prep is key.
My favorites so far:
Carnaubas
Zymol Vintage (I was given a sample as a gift): my car looks delicious in it, I have to admit; but I would never ever ever consider buying the stuff in a million years, even if I was super wealthy. I also had sweating problems for a couple days afterwards.
Souveran: I think (I think) I can see the glow people talk about.
Fuzion: wet look, so easy to apply and remove.
Swissvax Best of Show: looks great, but I did experience some sweating for a day or two.
Harly Wax: easy to apply and remove, nice balanced warm look--an underrated wax.
Synthetic Sealants
Blackfire Wet Diamond: the slickest protectant I have tried. My car looks gorgeous in it.
Ultima Paint Guard Plus: just so darn easy! For my wife's CRV, I really do want to wipe it on and walk away. No buffing. What could be better?
Mother's Reflections: easy to apply and remove, great value.
NXT: looks great, no complaints.
My search for the perfect wax will continue this spring. I still have a couple of waxes in my collection that I haven't tried yet (50/50, P21S 100%, Midnight Sun, and Lusso Oro). I really wanted to avail myself of the Souveran BOGO this Thanksgiving, but I simply couldn't justify the expenditure when I still have a quarter of a tub left and I have so many other protectants in my collection--but I love Souveran! I also want to add Victoria Concours Red and Collinite 915. Don't ask me why. It's a sickness.
