I'd have to agree with what StyleTeg said. You can't go wrong with zaino/blackfire/klasse as a polymer.
If you dont want to spend a lot of money, I'd recommend Meguiars or Mothers phase systems. Meguiars has the ABC system, whiles Mother's has the pre-cleaner/sealant/carnuba system. For the money, both are very good and give you a good shine.
I'd also recommend getting an random orbital buffer, which makes buffingthe car a lot easier. Get a Porter Cable 7336SP, its the best out on the market. Also, dont get a cheap single speed buffer, it'll do more damage than help.
Lastly, Zymol, cleaner wax, the green stuff, is a decent wax for the price, however I found out that is made and distributed by Turtle Wax to be sold at chain stores. So the Zymol most people buy, isnt like the $7000 wax that gave the company its reputation.
