If you are a car fanatic and love to detail your car, there are several steps you may consider. First of course, is a good wash with a quality car soap. I prefer Meguiar products but have been trying out the new Mr. Clean. Surprisingly, this Mr. Clean soap does what it advertises. Wash and let it air dry. Come back, and not a single water spot. Not bad.
Now, once you wash the car, you run your fingers lightly on the paint to "feel" out any rough spots that your soap may have missed. For this, you use a clay bar to smooth out the paint.
At this point, you are ready for a good polish/cleaner to "prepare" the paint for waxing. This will bring a bit of shine, but really plays the role of a primer in preparation for your wax of choice.
The glaze/sealant step would be next, if you choose to do this. Basically, you glaze your car to restore gloss and fill surface scratches. It also serves as yet another layer of protection for the paint.
Finally, you finish up with a good wax. Some people swear by carnuba waxes such as P21S Carnuba. This one leaves your paint looking as if the paint was still wet and very slick. Other wax systems, such as Meguiars new NXT series, are more durable, give you a deep, gloss that really stands out on darker colors and are cheaper/more accessible than the boutique brands.
So there you have it. A condensed version of a car fanatic's detailing steps.
