I am no Phil

but, it all depends on your expectation as far as how good you want to make it looks.
I'll do the usual, wash, clay, pre-wax clean, seal/wax. Most of the time the car would look very nice by then.
If not enough then you'll need to get polisher but check with Phil if he can get you anything that 220V/50Hz else you'll need step-down converter. (not sure if Flex with micro controller is OK cause it expect 60Hz while Asia is 50Hz even if you can step the volatge down to 110v w/ converter).

Just be careful this detailing thing is addictive.
