Sounds like you've got a solid plan!
Just a recommendation, I'd skip the drying step if you're going to go straight to claying (which you should.) As long as you are in a garage or working in the shade, the water on the surface will aid in the amount of lubrication for the clay bar, greatly reducing the amount of Detail Spray you'll need to use for the clay bar to do it's job.
Also, if you haven't already, be sure to cruise through our videos a few times before you start. Always nice little tips to be picked up there.
I've been checking through your videos and your forum as well as AutoGeek to get some ideas on the general consensus of how to do all of this by hand. I was going to leave the truck wet to aid as a lubrication for the clay, but I figured the additional water spots (even though I'm under a carport) would make claying more time consuming. We have plenty of humidity down here in Houston, but it's also still pushing 100* for a high, although I'll be doing this wash in the early morning to avoid some heat.
Also, I've been doing some research about Iron-X and was thinking of adding that as an additional step before spraying.
To the group: What's the general consensus on that product? Is it worth my time/money to add that step in before claying?
To Nick@Adams: Why does Adam's not offer a similar product to Iron-X?
