BTW, Interlux is owned by Akzo Nobel, who also makes Sikkens automotive paint. Sikkens is some of the best (and most expensive) automotive paint out there. My dad's shop used it exclusively for years until their constantly rising prices got too high to justify. A Spiess-Hecker rep came in and offered them a new state of the art mixing system if he'd give their paints a shot. He made the switch and never looked back ... they've had great luck with the Spiess-Hecker, too. Anyway, point being Akzo Nobel knows a thing or two about paint chemistry. I'm not hesitant at all to try this with the Interlux Brightside.
