What's your budget? For example I can recommend a wax at about £13 a tub which out performs a £40 wax. But likewise recommend waxes that cost £10k a tub. How long do you want to spend cleaning / detailing and how much effort do you want to put in?
Main thing is prep though. You can spend thousands on kit, but if you don't put the effort in you're wasting your money. Even on the cheap stuff.
