Many of us on this forum have learned a great deal from Canuck35G. I don't think it's being obsessive when we try our best to take care of a 40-50T dollar investment or when we are trying to learn the proper way to do so. The comments or suggestions were basically just another way to reduce a possible unnecessary problem. I believe his comment was general in nature and what could possibly happen when some (note some) person other than the owner or a professional is washing your car. I also look forward to any of your comments that will enhance my knowledge of car care. Cheers to all.
