Before I begin, let me just point out that I was not
one of the group of FTF SM's who received a free sample of Glow-On for testing purposes. I bought and paid for my own "kit" through their web site. And when I spend hard earned money... well, you know.
That said -- here are some observations I made regarding Glow-On:
My first test subjects are a matching pair of pistols, and a couple of common flashlights. The pistols are older surplus guns that have "dimpled" rear sight dots and a grooved front blade that are designed to contain a contrasting material from the factory. When I originally bought these guns and cleaned them the sights had some old, degraded yellowing paint in them. Cleaning solvent quickly loosened that material and washed it out of the recesses leaving me with bare sights. I had restored them by applying some Testors gloss white enamel (model paint).
I had asked Gato previously if I should remove the white enamel before applying the Glow-On to the sights, and he suggested to paint it on top of the existing enamel. So I decided to do a bit of experimenting. On one of the guns I applied the Glow-On over the white enamel. The other one I removed all the white paint, and filled the recesses fully with the Glow-On alone.
A couple of things I noticed were that if you have "dimples" to fill, the Glow-On will "sag" as it starts to dry leaving a concave surface. This is covered in the instructions
, and you simply apply more layers after it dries to fill in the center area where it sags. By the way -- it starts drying very
quickly and you don't get a whole lot of time to work it.
On a personal note: After I had built up enough layers to completely fill in the dimples, the dots had a bit of a lumpy, uneven, sloppy appearance IMO. I waited for about an hour for the Glow-On material to firm up a bit, then took a sharp blade and carefully shaved off the "dome" which left a nice flat clean looking surface, level with the sight blade. Just looks better to me that way. I let it cure for approx 20 hours before applying a couple coats of clear nail polish to seal the surfaces.
With that done I will say that there is a slight difference between the two (identical) guns now. The one with the white enamel undercoat on the sights appears to brighter - both in the light and in the dark, compared to the one with the Glow-On alone. Not a great deal brighter, but it is
My next test subject (Yugo 59/66 SKS) will get the same white enamel base coat before applying the Glow-On to the factory flip-up night sights on that rifle. They used a similar type of phosphorescent material on the issued night sights on some of those weapons. I believe that the Glow-On product is a perfect fit for that application in particular, for those folks wanting to restore their sights on those models.
Moving on to the adhesive squares / strips / dots:
At first I tried applying a couple of the smallest (1/16") dots to the flashlight. After cleaning the surface with alcohol and drying, adhesion of the teeny dots was..... lacking. After getting them to stick (barely) to the surface and applying a coat of nail polish to seal and secure them, they soon began sliding out of place. I know the adhesive is only to temporarily
hold them in place, but it should hold them (I think) well enough to prevent them from moving after being coated with the nail polish.
An attempt to re-position them with the tip of my X-acto knife only resulted in gluing them permanently to the knife tip because of the nail polish sticking, and making a gooey mess. Using the larger dot yielded better results - I assume due to the larger surface area and more adhesive. The squares and strips stick MUCH better than the dots do.
So far I have noticed that I get several hours of "glow" from both forms of the Glow-On as long as it is charged with direct lighting. After sitting items in a room with indirect (ambient) lighting the glow is greatly reduced and time is short. Which makes me wonder....
If I'm carrying one of my guns (concealed) for the most part and it's not getting direct lighting, would I rather be using the orange "Enhanced day sights" instead? And is that product even available in the liquid form? Additional tests may be in order.....
That's all for now.
