My 629 MG doesn't have an orange insert in the front sight like my 66 my failing eyesight can't see it....what is a good paint to use....

I've used finger nail polish or model paint a bunch.

We still discussing front sights.............

Hey, that's funny. Yes, we are still talking about front sights. No Bruce Jenners in this house.

Nail polish is enamel and it seems to hold up really well.

white fingernail polish.

Duh ...paint marker....I have some in white and yellow...thanks scottf

You are welcome. I have two in my shooting bag. The paint markers last longer than a lot of stuff and can me easily applied when needed.

I've been using Birchwood Casey paint pens. 3 to a package, neon green, white, fluorescent red. To me, the red looks more like orange.

Found the paint marker. White looke good....makes a world of diff...

It does for me.

I used fingernail polish on my S & W 642 38 SPL as a temporary fix. That was 10 years ago 😄.

That looks like good stuff. I am leaning toward green.

Did you put a white base coat down followed by another color? Did you pick it up local or mail order? Medium tip? I see Amazon carries it.

My machinist tool box had several in it when I retired. Not sure where or when I got them. I have only used the white and black so could not give real advice. I have used a lot of Dykem products over the years and never found any of their products to be wanting.

Yep..that's what I've used..now I can see the front sight a lot better on some of my rifles.

Thanks. Picked some up on Amazon, cheap too. After a little research it seems to be a popular paint for sights.

Use model paint on mine then a cost of clear fingernail polish on top. Nice and bright and lasts forever...

Believe it or not, I even used Tombow correction tape, then put a little clear nailpolish over it.

Acrylic if you are just trying out different colors.

i put some fingernail red polish on a revolver back in the 70's, and white model paint on the back. Few years ago it was still on there, and decided to take it off to see if it did anything. Nope, metal and finish was just fine.

I bought some chartreuse lure and jig vinyl paint, and applied it to the front sight blades of a Ruger Vaquero and a Kimber .22 conversion slide for my 1911 .45.
Visibility is excellent, especially against black steel plates.
