Invisible Transparent UV Reactive Blacklight Paint - (Blue)

*Updated 7/29/25 - Make sure you have the correct 365 blacklight as referenced by the manufacturer. THEN it looks just like the picture. It does what it says it would, but it is very, very pink. Nowhere close to the red in the product picture. I bought the green and the blue as well, for some reason one of those was opaque white instead of clear. It’s alright, but that’s all. It’s a little bit expensive to feel just alright about the purchase. *Update 6/28/2025 - Important to make sure you have a light source that really does have the 365 wavelength. It makes a tremendous difference.

I'm running 18 milliamps through a UV LED with a spectral peak at 365nm, which according to the documentation on this paint is short enough wavelength to exceed the phosphor threshold. There is no visible phosphorescence at all. I put three layers of paint on polycarbonate with a foam brush. The layers are thick enough they've trapped small air bubbles. When it gets dark enough I can test it more. If other people have gotten this to work I'd like to know what illumination source they're using.

Finally got to the point on my painting that I bought this for, and I was very pleased at what I found. I love that shade of blue on a black canvas, and it was easy to control the amount on the brush and it seemed to last a long time before reloading the brush. Great product.

This stuff is good, the color is more orange than it is red, but the glow is there and it's invisible as described. Just be aware that this is a lacquer based paint and not acrylic so you need some thinners for cleanup and flow improvement. But, it can be painted over if you miss, just make sure you have a blacklight/UV light handy to check your work. I'd give it 5 stars, but it came in an unpadded envelope so there is a lot of potential to spill in transit.

I was honestly a bit skeptical of this product before I bought it. But I knew I could find a million uses for it if worked as advertised. So I decided to give it a chance, and I'm happy to report that it really does work. Looks cloudy and yellowish in the bottle under normal light, but glows a nice neutral red under blacklight. It's very thick, which is great because you can thin it (I'm thinking this is lacquer based) and make a few large batches which will last a pretty long time. I've not tried airbrushing with it yet, but I imagine it'll work as long as you thin it enough. All in all, if you're curious about this, get a bottle and try it out. I'm pretty sure you'll be satisfied with it.

Bought to use under UV stage lights and alas, absolutely nothing happened. As in literally no glow at all. This product may work only with the specific high powered and close up UV light suggested by the manufacturer's description. I did not expect the stage lights to have as strong an effect as the photo but to have no reaction at all was wild. Honestly, saw more color on the paint in the broad daylight as I was painting. So buyers be sure to test it under the final conditions before you go all the way.

The blue and red colors are transparent, vibrant, and easy to use without mixing. However, the green one is not as clear, and I’ve found that I need to dilute & mix it the particles to make them work.

I use these to paint me fishing lures and weighted hooks so the fish can see them easier. I also have a UV light to test it. Wow. Very very bright and have already upped my fish count due to these.
