So Application, I'm just going to cover a few specifics to this paint.
It must go on VERY thick especially when thinned to be sprayable, For that reason Dont expect a lot of detail, youre going to need quite a few coats to get it solid and you may be forced to just Frisket and then do a little shading. In any event Its going to work best on a pretty large scale.
Black will only black out normal colors if they are painted over with white or some other bright color first so if you want to change the image or take an element out of it you will ned to first paint it white or blue and then paint it black. then you can use any glow color you want over top of the black.
Carefully combining your visible and invisible elements can make for some awesome dual images. Since no UV light is pure UV you can of course still see some of the things you can see under normal light.
You can create a triple image by using invisible glow in the dark paint and then going over it with invisible black UV paint. For example You could do a beach scene then use invisible glow in the dark pink and orange to create a sunset, then use invisible UV black over the Glow in the dark paint , then use invisible UV colors to bring out the moon and stars in blacklight. So you get daylight in normal light, sunset at dark and nighttime in the blacklight.
There is a fine line between having this paint be thick enough to create a solid effect and having it be so thick that your daytime image is all milky looking..... experiment some before you do a project that matters.
All of this stuff is a compromise, you will feel like your trying to paint with crap you made from berries and tree bark and urine. It's not nearly as easy as using regular paint. It can be very limiting.
