Update all-
So, I started to research a blower, and that's when I remembered my GIANT craftsman shopvac has a detachable motor with a cone shaped attachment to make the insane blowing even more intense. I tried it last night and it really blew the water out of the cracks well! The "bad" thing is that by the time I got around with a MF to clean up the small stuff, many of them dried and left small spots. I don't think I could blow the car 100% dry in a reasonable way. While the blower I have seems to really, well, blow, I'm not sure another product would do much better.
I also happen to have one of those super old school Mr Clean carwash hose things that has the DI filter in it. I must say, it seems to work the "best" with one exception. The mist of DI it puts out is very fine and it's SOOOO hard to trust that it will be spot free. There are a couple of pesky areas that water just hangs out in and with the DI water I don't have spots the next day. With the hose water and even with a super good blow dry I have spots the next day.
I'm leaning towards DI being the right answer. Especially since I already have a blower that seems to work sorta well. My guess is with DI and the blower, I'd be better off. Yes, I put a nice coat of sealant down, and yes use the right wash methods. I do like the idea of using a liquid wax at dry time, so I'll look into that too.
Thanks again!
