There's no question about the experts and the pseudo experts spreading a lot of confusing/misleading and sometimes just plain wrong information, but.....
The whole detailing terminology tends to be confusing.
Especially to the newbie, but it isn't all that cut & dried to those that have been around a while.
Polishes: A real catch-all. Zaino and Meguiar's both use the term to describe products intended for totally different functions.
Wax: Used a lot to describe what is actually a sealant or a synthetic blend. There's probably not very many so called "pure" waxes sold.
Buffing: Anything from a light polishing to a heavy compounding.
Buffer: Seems to apply to about any power tool that will rub a product on the surface.
Waterless Wash: Used to describe rinseless/low water usage products, products that don't need water added, but may actually contain water in their make-up, and products that are truly water free.
Chamois: Catches everything from the true Chamois skin through the synthetic chamois and the cloth chamois.
Swirls: Often used to describe just about any paint defect.
One step, two step, three step: Does this mean you can polish and wax your car in one step? Two steps? Three steps?
Silicone: Another one that is often misunderstood. Lots of products contain silicone. Containing silicone doesn't make a product bad.
Solvent or Petroleum Distillate: Here again, often used in a derogatory manner. Used properly, they definitely have their place.
I guess my point if there is one, is don't worry so much about what something is called or what's in it.
If it works for you, that's what matters.
