I agree that car washes with brushes are a NO-GO. But touch-less washes can be fine. Find a reputable one and stick with it. I found one i like by going through it with my wifes car and saw it was touch-less. Did some online review checking as well. You will be fine. I agree that automated washes will certainly strip off waxes and sealants faster than hand washing will. But today's waxes are now so easy to apply it's worth it for all the labor you don't have to do hand washing.
As an example of one of the dozens of protectants, The new hybrid ceramic from Meguiars was tested in both the spray on and the traditional rub on versions and the spray on version actually performed better. It doesn't get any easier than that. Every other month hand wash your truck and while drying spray this stuff on and your done. Full paint protection and keep going to the car wash stress free. When i was younger i used to love hand washing my cars. But now i'm older, tired and have kids and well water. I just can't.
My buddy has a BMW in that charcoal metallic which shows every little scratch and his car looks like new and he goes through the car wash literally 5 days a week.
Just my 2c.
