The product is fantastic! I am very glad that I took the time to read up on how to use it on their website, or I might have not had the best results due to my lack of knowledge.
About the product:
The glow works even in a regular light, but is not as bright as it would be if you had a UV light or such. This is clearly stated from the get go, so I was actually rather pleased with the amount that it glowed. It measured up to any "Glow in the dark paint" that I had picked up at a much higher price in a store... and beat out the regular craft store "Glow" acrylic with the first coat. In regular "daylight" led bulb, this glowed for about an hour after a few hours exposure. It was a dull glow after about 30 minutes, but still a glow.
The texture is slightly gritty... and I do mean slight (as in less than the finest grit sandpaper). This, again, is stated ahead of time. It is akin to any other glow product, and when a gloss is applied over it, it isn't noticeable.
There is no discoloration of the product with 5 coats applied. Due to the nature of the material that I work with, extra coats of paint are needed. This would cover porous material with much less.
It doesn't take much of the powder mixed with a clear medium to get the desired look. While the initial cost may seem pricey for the amount (I didn't think so, but some folks did), it really isn't that bad compared to other sites, and the product is high quality.
In closing... I can't state enough how much I enjoy both this company and the product. As an artist delving into new art styles, the fantastic customer service made me feel confident on trying my idea, and the product will be soon used for it's original purpose instead of fun little test projects.
