Listen to the Junkman. You can either be a detailer, or someone who just clean's cars. You'll find that people will go far and wide to have their car "detailed" by someone who knows what they are doing. Not only that, most will pay more for it.
You should also look in to Meguiar's professional line of polishes if you havn't done so already. The m105 & m205 is a pretty good combination for more paint repair work. Stick to a flex polisher or DA polisher (like the Porter Cable 7424) for now though.
Check out this site. They are a forum sponsor. They sell detailing products but also run a detailing shop. Amazing work.
