To all who like using marbilizer. A few years ago I painted a Sportster tank that had some marblizing in the graphics. The customer wanted something cool to make it stand out so I mixed some house of kolor glow in the dark powder to the marbilizer. It didn't effect the regular color of the marbilizer and it did have a noticeable glow in low light like in bar parking lots and such. It actually worked very well. I will see if I can dig up some pics of it.
