Benefit of dark wax?
 

I'm about to have to buy a new thing of wax and was wondering if there was any real benefit to "dark colored wax" or is it just smoke?

Certain waxes (with different chemicals inside of course) do better on certain colors of cars, that is true. As well as metallic paints and so forth. But certain products to be aimed at certain colors? Depends on the type of product.

I do know people who have used the "White wax" on white cars and they do claim to have a deeper shine added to the color. I always felt depth in white with wax was always difficult, but yet again depends on the paint.

for the most part I think its just marketing. the difference between how most decent waxes / sealants look compared to one marketed for dark colored cars is not very much. Most eyes, including my own on most occassions, couldn't tell you which wax is on there

its all about the prep. the paint underneath is what matters. a 2 step correction with spray wax clearly will look better than a old neglected swirly finish that has a coat of Wolfgang Fuzion on top (WG Fuzion actual retail price $195)

I'd pick up something easy to use, that has some cleaners (these products are often called 'all in one' - basically cleaner wax) Poorboys polish with sealant comes to mind. Klasse all in one if you want more cleaning action then remaining protection. Once the surface is squeaky clean with a base layer of sealant, then top it with something that has no cleaners. Collinite 845, p21s, whatever you like. You also probably should consider a decon step with clay bar prior to the cleaner wax

It's snake oil. Dodo Juice confirmed this themselves and they make a wide variety of colors.

If you're talking specifically about the new Meguiar's "White Wax" and "Black Wax", you can use either on any color. Here's the scoop on those...

White Wax
As we're all well aware, lighter colored vehicles don't have that deep shine. The "white wax" is focused on these vehicles. Since it is difficult to get white/light silvers/etc that deep, reflective shine, the white wax focuses more on defect corrections in the paint(swirl marks and the like).

Black Wax
The black wax is obviously made for darker vehicles. It has a much higher amount of polishing oils in it rather than abrasives for defect correction. This adds to the depth of the shine.

Both white and black wax do offer some protection, but personally, like other "all in one" waxes, I'd add a 2nd coat of something on top. Clear as mud? Basically, the white wax tries to clean imperfections in paint since light colors don't have the depth, while the black wax focuses on depth of shine rather than defect correction. I must add the caveat that the above refers to ONLY the meguiar's "white wax" and "black wax". I do realize other companies do have waxes they market to specific colors. I have no experience with those.

Here is a picture of my cousin's Impreza that I did a few weeks ago. It was in shambles before (she's brutal on cars and it literally hadn't be washed in about 18 months of her owning it and she's the 2nd owner). I used a clay bar, meguiar's white wax, then meguiar's nxt 2.0. From where it started, this is amazing to me.

Hope I at least provided a little info for you!

Turtle wax makes dark wax as well

I was going to try it just to prevent seeing anything I may miss removing.
