I keep reading so many posts where people use a :waxing:... but I can't afford one yet, and not so much that as I wouldn't want to "practice" with it on the car I want to make look brand new... So, basically I'm wondering if I can get great results with just towels and a little perseverance? Are there any products that I should specifically not get because they require a PC? I was going to get Klasse AIO but read somewhere that you need a PC to make it do anything. Please advise
