I have done a couple of my bottom feeders and I do all of my snubbie sites with bright neon orange and hi viz yellow nail polish I stole from my wife when I saw how bright it was. It was $4.00 for both containers at Wal Greens. It is ultra bright, extremely easy to pick up and aim against backstops, and extremely hard and durable. It has made a big difference on my auto loaders and a massive difference with my snubbies. I highly reccomend it. The nail polish I use is called Sinful Colors Professional #53 Summer Peach and #56 Neon Melon. They are as bright as any paint I have found and its only $1.99 per color at Walgreens. I tape off and take the brush out, wipe it clean, cut it at an angle, brush a light coat on and let it dry, then put a second light coat, once that is dry I put a heavy coat and let it dry overnight, I take an exacto blade and very lightly trace the tape and then take remove the tape and clean up any excess with a q tip and brake parts cleaner. A few days of wearing in and its very hard. My 5906 has been done for over a year and I havent had to touch them
up and my EDC snubby is going on 4 months in and out of various holsters and cleanings and they are still the same as the dayli did them.
