Has anyone used the Optimum Car Wax? I just used it an learned it can also be used as a drying additive. Also good for glass as opposed to older style wax. Obviously not ceramic-infused or anything but from what I can tell it leaves a very glossy, slick, hydrophobic shine. For less than the Opti or Hyper-Seal.
Yes, it is a great product. I have been using Optimum Car Wax for several years as a drying aid on my coated cars. It is a hybrid spray wax that has no carnauba in it. Being a synthetic wax, it has much better life span than than a traditional spray wax but if you are using it as a drying aid, durability really only matters for the time period between wash to wash. If you were to use it as the only protective product (no ceramic coat, etc.) on well prepared paint, it would last ~4-6 weeks without difficulty...perhaps a bit longer. It does leave a glossy and slick finish -- looks great.
OCW is easy to apply, economical (buy a gallon on sale for like $38-40), has a pleasant smell, and can be used safely on all exterior surfaces.
