So as the title says are automatic car washes okay? My water at home sucks it's very hard and leaves a residue. Would an auto car wash be alright? I plan on using the car wash then clay barring then polishing then waxing then doing a clear/protective layer. Or should I just use the self service bay? Ps I live in a very small town and am friends with the owners of the wash so I know the days it's cleaned and what soaps and stuff are used!
