Please let me step in here and make a suggestion on these dyes. For outdoor use you need a synthetic dye that is design & used in the custom auto painting applications. It will far exceed those original dyes in light fastness. What you should try is just the concentrate (although, you can purchase by the quart mixed in a urethane resin), and mix it with whatever clear vehicle you want to use: lacquer, enamel, urethane, and so on. Here is a link to the House-Of-Kolor web site;

You want the item, "INTENSIFIER™ KANDY KONCENTRATE (KK)"
It comes in 20 colors (which doesn't seem to be on the web page). I have their catalog if you want to know the colors, but they have what you need.
