Hey mate,
Dr Detail, definitely has a very good reputation.
I got him to come take a look at my V35 when i had it and i think the quote was around the $300 mark just to remove the swirls and nothing else. Being a bit of a tight ar$e at the time, i decided to give it a shot myself.
Started off very slow and just worked my way through the car.
I used a very very fine swirl remover with a rotory buffer at first. Not much result so went with a slightly more course swirl remover. Much better. went back to the fine one to finish it off.
For the polish and sealers, i used Zaino which give it that very "wet" look, and lasts very long.
Any way, long story short, 2 days of hard work in the garage!
The end result. I loved it!
As for the $400 a tub wax, swisswax make a massive range of products and believe me if he uses the $400 wax, you will pay for the $400 wax.
