TestorsEnamel Paint Open Stock .25oz-Yellow Fluorescent

Used this to fill the iron numbers on my golf clubs. Perfect!

An old favorite from my childhood, called to duty on my Ruger LCP II. I drilled 1/16" (0.063") dimples on the sights very carefully to set the paint into so they cannot easily chip off the surface. Discovered it does not flouresce on shiny surfaces but lights up brilliantly on white when I wiped the toothpick i used to paint with on a paper towel. Ended up painting first with flat white enamel spray paint from a small paper cup, then the yellow. Spectacular! What a difference in target acquisition and accuracy!

If I could rate 0 stars, that would be appropriate. This is a small bottle of liquid with food coloring in it. It’s not paint. It’s transparent and runny. Complete scam.

Testors paint has always been easy to use. Covers well. Definitely recommend it.

Works great for my gun's sights, as with all florecent paint it takes a couple coats to cover well.

The white dot on the front sight was dull and difficult to locate with my elderly eyes. After mixing the paint with a tooth pick, I applied a dot of the Yellow Fluorescent Paint with a new toothpick to the front and rear sight dots and allowed to dry overnight. I'm able to acquire a good sight picture easier now.

This stuff is quite runny and if it runs off what you paint that part won't glow in UV but if you can get it to collect on something or paint on a horizontal surface then it will glow pretty good. If you're painting something vertical it may just need a lot of coats. The size is very small, the picture has a AA battery next to it.

With an undercoat of white, then a few coats of this yellow. Bam! I can see the sights again.
