Hello, guys, can you help me over here?

I'm going to start waxing and polishing my car, so I'm interested in one specific question... Should I apply for this service and buy these products or not
http://colourshield.com/? Have anybody tried to do it already? Any suggestions, advices or preventions? I would like to read all of them. Thank you a lot for your response. I'm looking forward hearing something essential from all of you.
