Let me start off by saying, you have not chosen a "color"... You have chosen a hobby! It takes a lot of work to keep it looking good, but its well worth it!
Klasse All-In-One is a great product. It is a Synthetic Acrylic Sealant and Abrasive Free Polish that provides about 3-5 months of protection when properly applied and cared for.
Product:
Klasse Kit, klasse car kit, klasse car care kit
To paraphrase the above posts, you will need to wash your car with a quality car soap.
Clay bar the entire vehicle (if you need instructions on proper clay bar application, see this link:
Auto detailing clay, detail clay bar, clay lubricant, Pinnacle Poly Clay, Wolfgang, auto detail clay, meguiar's detailing clay, auto clay bar )
Put your hand in a plastic sandwich bag and slide it over the paint. It should feel perfectly smooth. If it does not, clay bar the tough areas once more.
I recommend using IronX as well, but it is optional. It removes Iron deposits that cause rust. Very effective, especially if you live in a harsher climate or near a railroad. Info on that can be found here:
Iron X Iron Remover, CQuartz IronX, Paint Cleaner, paint decontamination
After you have completed that, you can begin applying the Klasse All-In-One. Take a microfiber applicator pad and moisten it with quick detailer, apply NO LARGER THAN A DIME size of Klasse to the applicator pad. Believe me, you DO NOT want to apply too much. Its better to have to reapply a little than to take excess off. If you are looking to really extend the life of your work to well over 9 months (as long as 12 months, depending on your climate), you can apply an additional coat of Klasse High Gloss after the Klasse All-In-One dries for 12 hours.
Once this is applied, you will not need to wax the vehicle at all. Just an occasional wash or some Quick Detailer if you're going on a hot date. This stuff is great!
Good luck.
