Yes. I forgot to mention that. NXT is probably the easiest polish around. Sray on. Leave for five minutes and you dont even need a PC etc to get that shine. Just a soft cloth does wonders (Microfibre cloth).
The stores here dont seem to stock the liquid anymore. Only the spray on version. What would you all suggest to use as a polish/wax for a machine polisher/ PC?
I am planning on buying one soon and may be detailing a few Lambo's, Aston Martins or Porsches soon so advice would be great.
Please dont send me to Detailing World.... Them members there scare me 
I'm no expert by any means, just an "enthusiast", if anyone spots any mistakes feel free to advise.

As a good place to start, the 3 step Meguiars product does quite a good job, along with either a Porter Cable 7424, or the new Meguiars G220. The Porter Cable is American so you will need a 240/110V transformer, the heavy yellow things found on most building sites. You will need to change the plug from a US to UK 110V 3 pin, about £1 at most electrical stores.
The G220 is a new UK product, I haven't seen or used one yet, but I can imagine it does a decent job, as their products are top notch and well priced compared to Zymol, Swissol etc.
Start with a clay bar and quik detailer, your paint will be as smooth as glass. All the instructions are on their website
