I'm not a "wax expert" but her ya go...
Zaino is the best, but your looking WAY into the 3 digits for the whole kit. But enough layers of Zaino is supposed to be just as good as a whole new clear coat.....it's that damn good.
Mothers and Meguirs is good. I use the 3 step mothers process on my car. Prewax, glaze,and REAL carnuba wax ( not the synthetic stuff). Initially the mothers will cost you about 50 -70 bucks. But it lasts. You only need to prewax say once in the spring, and maybe near the end of summer. Although, I only use it in the spring
The sealer/glaze is about 10-15 bucks
The wax is about 25-30 bucks all Canadian of course.
Prewax was about 8-12 bucks. This is NOT the same as dish liquid as some fools will try to tell you. It basically strips the old wax, and grime, tar, oxidation etc or whatever off of car so a new fresh coat of wax can be put on.
I glaze and wax once a month by hand. The glaze gives it a nice wet look and seals fine scrathes or swirlies, and the wax seals it and protects it. Never JUST glaze, or the rain washes it off. One bottle of Glaze lasted me ALL last summer, and still have some left. Granted, our summer is April To Sept, although I keep waxing up to beginning of Nov. The carnumba wax doesn't last as long eithier. I also used it on my wheels. I'm not sure of the finish on your racing harts.....so I'm not sure if you should do that. Pretty safe with real carnuba waxes on wheels....just don't use some synthetic fake crap on them or you'll eat the finish right off. I wax my wheels to keep them from pitting, and little rocks from chipping them. Also makes them very easy to clean. If your wheels are the same type of finish as mine they are REALLY easy to scratch....only use the softest mits or cloths to was them with. And make sure your mit is SOAKED before putting it to the wheel.
I also use Meguirs scratch remover on any small scrathes on car (I have like 3 scatches on it so far...I'm lucky...knock on wood) Follow this stuff with wax as well or it too washes off quickly.
I use Mothers because it's easy to get where I live, and it's not supper $$$$. If money was no object, and I had a heated garage, I'd use Zaino. You REALLY need a garage to let car sit over night with Zaino products.
That's my 2 cents
3M is good as well. All these products the guys mentioned are great.
