i would add in Iron X after the wash to make sure the paint has all iron contaminates removed then clay the entire car.
Pictures would help, seeing what the swirls look like would help in deciding pads and polishes. If the swirling is very light you could use a one step product like Pinnacle...
Rattle can spray paint is basically a thinned out single stage enamel. It will take about 30 days to fully gas out and harden. After this time period you can wet sand, polish or wax it like a normal single stage paint. It is softer then single stage enamel as there is no hardener in it.
Wow only 30k? not including building? still if that is even close to the mark its a steal. After my collision shop burned down i got 250k from the insurance and i need another 150k to start up again.

today sprayed a front clip for a chevy cobalt.
finished buffing out a new carbon fiber hood for a 5.0 mustang
and removed the damaged front clip from a ctsv caddy.
(god i miss working for myself)
Also do not try and polish in direct sunlight, the panels will be to hot and the polish dried up real fast. If the panel is to hot to hold your hand on for a few seconds its to hot to polish as a general rule of thumb.
