I have noticed that glazes are nothing more than a superlight abrasive with an "oil" in them that deepens color and adds a gloss. It will wash off most of the time. I have also noticed a disturbing trend in waxes and polishes. They seem to be all moving to a chemical type that softens and swells paint to hide scratches. Very disappointing as I started detailling and buffing out fresh paint right about the time that junk started appearing. I had my favorite of all time, 3M's Finesse It, soften the paint on my Lemond. It did NOT do that 15-20 years ago when I was working in body shops.,,,,BD
