"I'm not sure what kind of velocity those dryers are putting out, but I can't imagine it being much more than what you'd see at 130-160 mph out on the highway."
Exactally right. I've owned 3 Z Roadsters. I treated all 3 tops with 303 when I got them and after that, forgot about it. I use a pressure washer on them with car wash soap just like I was washing out the wheel wells. Never an issue or a leak. Even though the tops may look fragile, they're not. I've driven the wheels off of all three, burn regular fuel, and never put baby oil on their bottoms to keep them dry.
Though opinions vary, at the end of the day it's still just a car. A truly awesome car, but a car just the same. Treat it like one and you'll be much happier with it.
"never bring your car to a hand car wash, period. you never know how many times those rags been on the ground"
Also exactally right. I've seen people start at the bottom where all the grit is and wash their way to the top. Really? Or even worse, wash out of a bucket of mud.
So for me personally, if it's too cold to hand wash it myself, then I let it stay dirty until it warms up. Dirt sitting on it isn't going to hurt it, but dragging that same dirt across the paint will. Just my 2 cents.
