if you clean and degrease the blade GOOD, about any of the model paints, even nail polish will stick ( adhere) put on thin coats, maybe a couple of them , let them dry and set.......lots of colors out there, extremes too, like the "day-Glo ' oranges, etc........no need or reason to change sight blades.....the thing you will find , is what the colors appear to "look like", at different times of day, high noon, dark, dusk etc...this is where the trouble lies. as well as the target itself, and the back ground......contrasts and things blending in, trick the eyes.......I tried many over the years , and have gone back to plain old black, I want the front and rear to match on the target...now for 'combat' the three dots seem to work about the best, but the "dots" are a whole different concept than 'paint'....for 'defense', my carry guns, I do not even use the sights...so go figure.
anway with any of the paints, you can do them over and over, till YOU find what works BEST for YOU......
