I was considering spray painting my kanger protank 2, specifically the lower portion and the part above the glass tube. of course i wouldn't be painting the drip tip, glass, or the lower screw bottom, I would also mask off the internals of the tank. Has anyone ever done this? Of course there is always that concern of inhaling some of the dangerous chemicals in spray paint, or it coming off on the users hands. If not, is there any "colorful" tank that I can buy that is compatible with kanger coils?
