bill_de you forgot to use "sarcasm quotes"
It's interesting that the company that produces Opti Coat still sees a need to produce and sell a wax product:
"Optimum Car Wax (OCW) is the only "spray on" wax that provides the durability of a paste wax and long-lasting UV protection.
It contains a combination of high-grade Carnauba wax, sealant polymers and UV inhibitors to form a protective layer on the surface and protect the paint from sun damage and environmental elements for up to 5 months.
Some key benefits to Optimum Car Wax are:
Easy to use and takes less than 15 minutes to wax a complete vehicle.
There are no buffing of wax residues to deal with. It is a simple spray on, wipe off formula.
One application lasts up to 5 months
Helps reduce fading
Contains no harsh chemicals or VOC's
Won't stain plastic trim - In fact, you can spray Optimum Car Wax on these surfaces too to protect them!"
It appears even they realize that no single product is the be all and end all or they wouldn't make and sell both options.
