Jake, I hate those water blades....... all it takes is one little errant bit of something under it and you're screwed. Do this instead: after your final rinse take the nozzle off the hose and turn your water pressure down to about 1/2, then hold the hose close to the surface and parallel to it so the water runs out onto the panel in a gentle stream. On a well waxed surface this will sheet the vast majority of the water off the car, so instead of having to dry a billion little beads of water you've got just a few big ones. Use a couple of waffle weave microfiber drying towels to pick those up and you're good to go.

By the way, I've got a 2004 PT Cruiser Turbo in Graphite Metallic and the last time I machine polished it was over two years ago and it has barely a mark in it. I use Ultimate Quik Detailer and a few microfiber towels to clean it off several times a week and only wash it once a month at the most. I've got a write up on this over at meguiarsonline.com.......... I'll copy it over here in the next few days as a guide to maintaining your finish once it's dialed in.
