You guys also have your hands full because the all Nissan makes have hard clear coats, not Vette or Mercedes hard, but not soft making polishing out swirls much harder. Like some of the posters mentioned previously, the Menzerna line-up of polishes work well, they were invented specifically for German hard clear coats for Mercedes. The 3M line is very good too, especially Ultrafina for jeweling the paintwork. Meguiars new M105/M205 combo is something to look in to also, it' my go to polishes and they are very good. Some rules to follow:*Always use two bucket method with grit guards*Try to get a Gilmour Foam gun to get the loose contaminants off before you even touch the paintwork with any wash media.*Get dedicated MF towels. Make sure you use Plush waffle weaves, not a chamois, they tend to trap dirt and you'll be sanding your car with the chamois.*Use a high quality shampoo. If you want to only use OTC products, go with Duragloss or Meguiars.*Remember that wax makes up about 2-5% of the cars overall appearance. It's all about the prep before you get to the LSP stage that gives your car its look. After you wash correctly, you need to see if you want to clay bar the car(you don't want to seal in all the contaminants even more by waxing a contaminated car.) Don't assume after claybarring you can go straight to wax, the product manufacturers would love for you to think a wax can correct paint, but it is merely a protective layer between the paint and the elements. *After wash and claying look at the paintwork under halogen lights and you'll probably be stunned at how many swirls are in your black car. I use a 3M sun gun, but I don't think many enthusiast on here will pay $400 for some light. There is a Brinkman you can buy for around $30 at Pep Boys and it will suffice.Don't forget polish and wax are two different things for different purposes*For novices or weekend detailers, I would recommend polishing with a Flex 3401 or a Porter Cable 7424(cheaper but effecient) with an assortment of Lake Country pads. With the right pressure(20lbs) you would be suprised at the level of paint correction you can achieve.*Look up Tasko Auto Color . They have many locations and if there's one in your area your in luck, just about everything 3M and Meguiars makes, they sell.*Yes, dry off with a leaf blower, once you do get your car slick and detailed, you'll notice that you can almost dry the whole car with it, and you definitely need it for getting water out of cracks, mirrors, and emblems.*When you do the final rinse of the car, take off the sprayer and just let the water run over the car, from top to bottom of course. This will sheet off the water and your towels won't fill up with water so quick.*Between washes never touch the car with a dry towel. At the very least use a QD or you may want to look into ONR(Just Google it, you'll see what it's all about).*P21S is a great carnauba wax, but if you ask 100 of the best detailers in the U.S, you'll get 100 different answers. They're are many to look into. Actually, P21S is the same as S100, which is sold in Harley Stores. Collinite is great. Pinnacle Souveran, Meguiars #26, #21, #20, Dodo Juice, Swissvax, Zymo(Estate Glazes, not the stuff at Target)l, Poorboys, Wolfgang Fuzion, Zaino, Duragloss(Car Quest), Clearkote, etc , etc.
Remember, you can put a wax on a sealant, but not vice versa.
I know I've missed plenty, but this is all I have off the top of my head. I at the very least use this wash method on every car I recondition. If you want to know all the fact, myths, where to buy, what to buy, visit sites like
http://www.autopia.net or
http://www.autogeek.net These sites have how to videos, arcticles and anything you could possibly dream of for detailing a car. I know I have more to offer here but my brain's starting to hurt from thinking off the fly like this, hope this all helps a bit. Feel free to ask anymore questions.
