I haven't started using glitter in the powder yet too, many project in the fire. But know most of the people that use it use powder. Rad texan is a master of the glitter powder paint and know he gets his from Hobby Lobby. They mix it with clear coat. Have to read more on it before I do it. You can get some really neat custom colors.Do some searches on Glitter powder paint on this board and am sure that you will find out the answer to you question.I

I don't think that you are going to do it with vinyl paint. The only one that I thought that was good is a Red paint head dipped that was rolled in silver glitter while still wet. And that was really old school.
