detailing world forum has loads of reviews and products so its worth having a look online, i too will be looking ro buy new cleaning stuff.
ive settled with a autoglym full kit and still looking for what clay items to use,
make sure you buy lube though! makes a huge difference
also with the Machine polisher youll want a degradable abrasive
basicly it gets finer the more you use it which lowers how course the abrasive is giving a final better finish,
my mate did some on my white scala, it came right up!
but i would suggest reading up on it heavily first, you dont want to burn white paint!
also youll want to clay a car of its imprities in the paint before machine polishing
btw find out what rpm your polisher is it can make a huge difference in finish depending on how fast your polisher is to what abrasive you have.
