Back when I was just using a GG6 was usually something like:
Friday Night: Scrub/clean wheels and tires for Tuff Shine & Gyeon Rim application. Wash, Iron-X, Quick wash, Nanoskin mitt, Wash...dry. - about 4hrs
Saturday: Compound and Polish - about 10-12 hrs
Sunday: Coat, Tuff Shine Tires, Gyeon Rim Wheels, Gyeon Trim on plastics, misc cleanup - about 6hrs
This was all in my garage, tripping over cords, moving stuff around, plugging/unplugging machines as I moved around cars. One thing that helped considerably this year was remembering I had an 8ft table and setting it up in garage. Spend about 30-45 minutes getting out everything I think I'll need and organized...probably saved 2 -3hrs of just moving/resetting stuff in previous routine.
Now, I have compounded, polished and coated our Corvette one day in about 8hrs but I was hustling, not taking breaks, not wandering about...just busting it out.
Getting a Flex 3401 for the compounding, and a Rupes 15 Mk2 for the polishing step knocked a couple hours off of that, especially the compounding; strap a 6.5" pad on the Flex for hood, roof, trunk and 5.5" for vertical panels and if you know polishing is to follow (usually Sonax Perfect Finish on Rupes if paint allows) you can really knock out the heavy stuff with the Flex pretty quickly. Bit of a workout but fast.
By the same token, on our personal cars that can be outta service for a week, I took 2 weeks to do the Corvette. Maybe one panel a day/night...nor reason to hurry so why knock myself out.
