First welcome to the forum.
White is not really any different then any other paint, it's all clearcoated except with VW's the clear is typically very hard, so you'll need something strong.
I would suggest getting a claybar to start out with and going over the car good.
If you still have blemishes, then I really love the Menzerna IP and PG line for polishing out scratches and oxidation and such.
Zaino ZPC/Fusion is also good. With Zaino though, it's best attribute is the sealants, Z5 and ZCS are top of the chain durability and long lasting shine.
Stay with the forum and keep reading up since there's a million products out there.
