I apologize in advance for posting a problem on a Pcar and not a Ferrari but since they all have paint and this is a paint and detailing related problem I am posting here and invite the moderators to redirect this post to the right place. I am on a road trip enjoying wonderful scenery and twisty roads and then ... I check in to a Marriott. Here's the problem: Last night the hotel sprinklers came on and sprayed my car. By the time I checked the car late this morning the car was covered in white spots. The guards red paint is spotted, the black soft top is spotted white and the wheels are spotted. I have spent the day trying to correct the problem and nothing is helping. I finally found a "touchless" car wash and that didn't help at all. I have tried various wax products and nothing touches it. The hotel employees told me that they think the spots are hard water stains. Any ideas of what to do to get rid of the water spots? The spots are MAJOR spots and very obvious. Any help is greatly appreciated! I am panicked! Thanks!
