1) When i am ready to wax, do I need to use a buffer to buff out the wax when done or can I do it by hand? What is prefered for a new Porsche car Dark blue.
By hand is fine. Prefered is preference.
2) What is the differance betwen polishing and waxing? What is the Porter used for? The idea of using a drill type device on my new paint scares me.
Polishing is prepping the paint for wax. Most polishes are for removing marring, oxidization, etc. Basically cleaning the paint for the wax.
The porter cable is for polishing/waxing but by no means mandatory. It's also not a drill type device.
3) Since the car is NEW what should I look to do in the first 3 months? Washing is understood but does it need a wax? What about the polish?
Don't polish unless you need to. I'd say a nice
AIO (ZAIO,
Klasse AIO, Prime, etc) by hand would clean the paint up pretty nice and then top with a wax or sealant.
4) Does new car leather need a prep of any kind before i star tto use it for protection, or is it more a clean it when it is dirty type of thing?
Clean when dirty, protect when neccessary.
