Title: Wax applicator for car wash - with non aqueous wax solution sprayed on and heat polished by infrared lamps
Inventor: WEIGELE GEBHARD
IPC: B60S3/04
Filed: 1973-10-04
Abstract: The application of aqueous wax solutions provides only a minimal car body protection, with the wax not penetrating paint pores, and with most of the wax washing off. The invention provides a non-aqueous wax application, after the car has been blast dried. A pump draws wax solution, or even molten wax, from a reservoir and pumps it through a heat exchanger into an atomiser jet. The hot wax vapour is then distributed in an airstream inside a duct from where it is blown over the car in a curtain. More durable hard waxes can then be used for improved protection.
