Where can I find paint that glows in black light and is invisible in regular light?

Does it need to be paint? wouldnt a UV Thick Nib Permanent Marker *(5mm tip) do the trick? only costs a few bucks.

Have you looked at what this company offers? They’re $8 – $12 a bottle.

I used to work at Home Depot in the Paint department. Most stores will have that there, and I expect similar big home improvement stores would as well. It should be bright enough for your needs.

Tide liquid laundry detergent works great for this. We used to use it all over the joint when we’d throw parties. If you looked REALLY close at the walls you could see a hint of it in normal light, but once you hit the black lights everything was AWESOME!

I just wanted to second @torchingigloos‘s suggestion of using tide. It works amazingly well for this.

Great suggestions, guys. Thanks! I will try the laundry detergent. I had tested some out, but it didn’t seem strong enough. Maybe Tide will work best. I hear that if the detergent says “brightens clothing”, it will be more effective.

@incendiary_dan Cool! Can it be used on human skin, though?

@Odysseus That would probably work, but I wanted paint, because I want to apply it live, and I the drippiness of paint suits my purposes.
