have never used a coating before but would like to try to start upselling it. very small, nearly nonexistent market for it here, but think I need to have some on hand in case. what brand should I get for starting out. probably wont be able to keep vehicles overnight, so is there anything out there that doesn't have to cure? how do I use this new Gloss Coat? I really don't know much about coatings at all. aware me.
