Yes. If you bucket wash your car using our instructions (or just let us do it), your coating will stay in the greatest shape. Touch-free car washes are okay, but you never know what chemicals they are using, and you still get spots from hard water. Most automated carwashes use degreasers, which will break down the ceramic finish. A regular contact carwash will cause a greater reduction in the ceramic coatings’ longevity. We always recommend a 6-month professional wash and inspection.
