Unless you go through a brushless system, tunnel car washes are going to scratch your paint.
100's of cars going through, and those brushes are picking up dirt and grime. Unlike the two-bucket hand wash method, which get rid of picked up grime before reapplying soap.
The only way the auto car wash brushes get rid of grime is by rubbing it on your car.
