Is it ok to polish and glaze your car after you wash it??????? See my mom's car (2002 GP GT black) is getting hairline little microscratches in it and well we don't have a clay bar or cleaners yet. But what we want to do is polish it and then glaze it with some products like Meguiars professional hand polish, then follow up with Meguiars show car Glaze. So this is what we want to do or do we need to clay it and clean it before we go to the polishing and glazing??????
