I've got some of this stuff. I haven't applied it yet. The reviews are mostly positive.

I haven't used this particular product, but I have used other glow-in-the-dark paint on my sights. It worked some.... made them higher contrast; more coarse which can be a negative. If you want that stuff to glow, I'm guessing it will require a charge from your light. The stuff I used did at least. It would "glow", I say it that way cause it was pretty faint, for 15ish seconds. I ended up droppin the ching on night sites... mainly to duplicate my carry gun's set up. But, that kinda says something for how effective glow-in-the-dark paint is. On a side note, night sights aren't really that much of a benefit if you will be using them in conjunction with a light. Honestly a good set of three-dots, light, and effective, well practiced technique really can't be beat. But, I will still keep the night sights around in case I can't get to my light fast enough.

I wanted a better sight for my GP100. I thought about buying Bright Sight. Have any of you used this type of paint product before?
