All carwash systems use an acid based soap.
Acid removes the oxidation and dirt. The acid is neutralized with a water rinse and rotating brushes in the carwash. Remember how the DeLorean cars would turn brown after washing with dish soap?
Most cars are stainless steel with decals over the shell. Loco's are painted with the "wave" decal applied over the paint.
Some Heritage cars (diners and crew cars) have been painted in the past, but I've noticed that the cars have been restored to the stainless format during overhaul. Some cars may have bad body panels and may remain painted.
The decals are being used on buses and custom cars. In Miami, they seem to fade quickly from the sun.
I don't think there is a problem with a nose decal. All equipment has "swipe" ID tags on both sides and car numbers would be applied. #84 has small numbers applied over the decals.
Didn't Amtrak want to remove the ID light from the nose?
