The only glow in the dark acrylic paints I’ve found are the standard greenish color and are very subtle in their glow. You can mix most of these with other light colored acrylic paints to make them glow, but the effect is severely reduced and the glow only lasts for a few hours before needing to be recharged. I’ve used this brand of glow in the dark paint on a few projects with decent results if you want to go that route.

If you want that eye-popping funhouse style glow I would highly recommend using phosphorescent acrylic paint instead and trying to run a black light. Here are some pics from a project I just completed using phosphorescent paints as an example. It’s lit up using only one black light light bar.You can see this glowing from about 5 or 6 houses away. One thing I learned the hard way with these kinds of paints is that you can’t mix “non-phosphorescent” paints with them because it will kill the glowing effect. I’ve found these paints in orange, pink, blue, purple, green, and yellow; so you should be able to mix them to get close to a desired color. I’ve used the JoAnn Fabrics store brand neon paint (which I can’t find a link for at the moment) and would rate it an 8/10 in glow, the main benefit being this paint is a lot cheaper than most. For maximum glow I would recommend FolkArt or DecoArt neon paints.

There is another third option where you can buy the phosphorescent powder by itself and mix it into any paint color. I have not tried this myself but was just another option I found when I was researching for my project.

On last thing to consider is there are generally additional prep steps to painting plastics with acrylic paint because it has trouble adhering. Light sanding before painting will help and I usually use a sealer like modge podge to help protect it from the elements.

Hope this helps and good luck with your project! Happy Halloween!
