I give away my old detailing products to friends and neighbours it keeps the count down. I only keep the products im currently using. It also helps to stop them thinking im crazy as they slowly get addicted too.
As for drying, I do get a few odd looks as I blow dry the cars..
Ive never used automated car washes or any other type not because of youtube but because you just don't know whats in them.
I will try to blow dry my car next time!!. I haven´t used my air compress yet..
what about using one of these?

I don't think the Karcher window cleaner / dryer would be good to use on a car's bodywork. It looks as if you have to drag it across the surface to be dried, making contact with the bodywork; if so, it would be a great scratch and swirl inducer, and it wouldn't fit all the contours of the bodywork.
I dry my car by rinsing with an open ended hose to 'sheet' most of the water off. I then blow dry with one of these;

Any small amount of water drops that are left on the bodywork and wheels, I finish off with fluffy drying towels.
