Not all, but a lot of the "touchless" gas station washes use some rather harsh chemicals to compensate for the lack of any real brushes/rollers, etc.  They will certainly strip the wax off of your car (and skis).  I would be a little concerned about the lubricant in your bindings.  Check your binding for sure.  If they need lubricant, you want a heavy grease, not a thin spray on lubricant--those don't last very long.
