I've been watching a lot of watch polishing videos and in some of them parts are coated with a purple lacquer (picture attached). It's purpose is to protect logos, sandblasted finished etc from being removed by polishing. In one video this was called "Swiss secure lacquer". I'm unable to find this online. Does anyone know the name of his product or where to buy it? Thanks.
