Not sure how many of you are subbed to the /DRIVE channel over on Youtube, but they occasionally run this guy's videos. He's an amazing auto-detailer out on the east coast. Definitely seems to know his stuff and his videos give really great detail on how to do things. You can most definitely waste the better portion of an afternoon learning things and watching the videos if you aren't careful (yes, I'm speaking from experience).
Anyway, didn't see it posted up so thought I share. He does plug his supplies quite a bit, but still gives great tips and tricks.
