As it's a new car it won't need to settle, the paint will have been on for long enough now. You can start detailing her now!
Do you have any car cleaning products? If not, then the products can add up in value quite quick so it might be worth buying bit by bit. You definately need 2 buckets, a quality shampoo, a good wash mitt, and a good drying towel. This will at least enable you to give her a good wash knowing you won't cause any damage.
Then it's up to you to what polish and wax you want to buy.
There are also other products you may want to add like Clay, wheel cleaner, tyre gel, a glaze, a quick detailer, spray sealant etc etc.
If you want any advice for what products to go for, or if you have a few idea's already, drop me a PM or e-mail and i'll help out all I can.
