In-bay and conveyor operators have been using Rain-X (total body) since 2005 because it works well.
Value proposition is product repels water for up to 30 days and creates a little shine by leveling some of the microscopic imperfections on paint surface.
Requires one ounce per application average cost is roughly $0.50.
How it affects throughput (selling price less cost of materials) depends on the carwash operator and customer take rate.
If the price is $3.00 and take rate is 20 percent, average revenue would increase by $0.60 ($3.00 X 0.2).
However, if touch-less is leaving behind a film on the paint that is consistent with eyebrow on windshield, don’t expect the product to work as well or last as long.
Rain-X was designed to repel water from glass, paint and chrome, not dirt.
