This guy provides some information on the product. He mentions the cone nozzles that are on the ceramic sealant arch. If you get a look at their arch, you can probably see how they intend for it to be applied. Probably more than one way to do it though. He also says it can be applied after the
drying agent.
The information on the
Kleen rite site says 30 days of protection. That seems the same as hot wax and shine. This guy also mentions how it is to be applied only as a $5 up sell and should not be a part of any other wash package.
