If you are going to spend that much, here is what I'd get:
-Flex DA polisher - awesome machine, a must have, unless you are a rotary pro.
- Menzerna Nano Polishes - SIP and PO106FF. Or you could get Wolfgang 3.0 polishes, which are basically the same thing.
- Good quality MF, and lots of them, I' get them in bulk, spend $150-200 on them.
-Wolfgang 3.0 sealant, matter of fact I'd get it in a kit, with Wolfgang Fuzion
-Foam gun - a must, unless you have a pressure washer and a foam lance, which is even better. Also get DP Xtreme foam formula soap, Meguiar's Hyper Wash, or Optimum
-Pinnacle Souveran, again better off in a kit - more savings this way.
That should be enough to begin... Save the rest of money for later.
