Metal Polish not = car wax? same ma.. my project is low cost one, the mnpc all good stuff.
The difference between a Wax and a PolishWax is a protective coating that is applied to the exterior surface of an automobile to prevent oxidation. Wax does not protect against bird droppings, acid rain or tree sap. The only reason a wax is applied to the exterior surface of an automobile is to protect the paint or clearcoat from forming oxidation.
Polish is a cleaning compound that removes impurities from the paint which prepares it for waxing, sealing, or protecting.
They are very different and should not be confused, although the retail industry has mixed them up greatly in their advertising as having a wax that polishes too. However this is not possible because the substances perform separate functions.
Experience is required when working with polishes. Polishing agents remove oxidation, surface contaminants and also some of the clearcoat surface. An inexperienced polisher can create swirl marks on the painted or clearcoat surface. Fine polishing agents can create fine swirl marks.
Swirl marks can be hidden or masked when applied with wax but will return and become very visible once the wax wears off.
