the paint buffs to mirror so i see no need for a clear coat. they have a clear coat in the tremclad brand made for the paint but i don’t think it’s nescessary. i reciently buffed out a huge scratch when a guy tried to jump me at a drive thru atm (long story!!!) and i florred it ran over his feet turning tires, and pinned him between the wall and my car. the whole rear quarter had a really bad scuff, maybe it was his teeth and the buttons on his jacket, anyways it buffed right out, with clear it would be hard to do that. so i would say there’s no need for clear unless you really want a show car finish. thing i like about this paint ALOT is that there’s no need for primer, primer sealer, ect… it really simplifies the process. shooting a base clear or single stage acrylic enamel is a pain, u have “windows” to shoot each coat, and putting the primer sealer on, you have to shoot color within 30 mins or 15 days, man what if something goes wrong? lol
