I don't get paid by the company, but here goes what I know.
There are two main products I use that are designed for darker cars: Natty's Blue Paste Wax and a Polish with Carnauba Blue designed for darker cars. All other products are general use, and the regular Natty's and regular Polish with Carnauba are for light and metallic cars.
You are asking about products, let's take 2 categories: Polishes & Waxes/Sealants.
Polishes:
-The SSR series, Super Swirl Removers, is a series of various polishes with different abrasion. SSR3, 2.5, 2, and 1 are four steps, from heavier abrasion to lighter, in removing surface scratches and swirls. They take quite a bit of work, especially by hand or with a PC, but work well. They are comparable to cut polishes or compounds in other lines, but have the simplest system of understanding that I know. I don't prefer the dyes, but they work well.
-There is ProPolish, which is a commercially viable product for one step polish & shine. Quite a versatile product, but I have little experience with it. It would be a step less abrasive than SSR1.
-My favourite is the Polish with Carnauba, which takes out the scratching you can't see and leaves a nice gloss. Blue for dark and regular for the rest, they work well. Not wet like a paste wax, but glossy. Apparantly the Polish with Sealant is coming out this spring. A great product, very easy to use by hand or machine, but I'm concerned about following with a sealant, so best to follow with a wax.
Waxes/Sealants:
A wax is a natural Carnauba product that gives a nice warm, deep glow and protects for 6-12 weeks. A sealant is a synthetic product that gives a sharp, glossy shine and protects for 3-6 months.
-Natty's Blue for Dark and regular paste waxes are very easy to use, dry in 30 mins, and easy to remove. They smell great too, and give the shine I like. I don't know how long they last, but as well as any wax I believe, and cheaper than many paste waxes.
-EX is a sealant with Carnauba for a warmer look in a one step application than many sealants I've tried. It works just like a wax--most sealants do--with easy on, haze, easy off steps.
-EX-P is a pure sealant without Carnauba and has no cleaning properties. It has probably the longest protection of the PB's line, and can be followed with any wax I've tried.
-QW+ is Quick Wax Plus, which used to be QD+. It works like a spray wax or QD, which I am a fan of neither. I haven't tried it, but have some.
If you are a monthly waxer, any product will work. The one rule is that waxes can top sealants, but not vice versa. Play around, and let us know how it goes.
