Any suggestions on covering up the back two dots, with the ability to uncover at some point in the future, only thought so far is to use my kids paints.

This.

 

The white dot in the front sight of my M&P flew out the first time I shot the thing. Used some white nail polish, years and a few thousand rounds later and it looks just like it did before the dot flew out. I'd imagine some black nail polish would work equally as well. Then some nail polish remover or some white nail polish over the top and you are back to normal.

Good ideas, thanks to all.

I use white crayon to freshen up my dots. Don't see the harm using black crayons. When you're tired of it, pick it out with a toothpick and pick your next flavor.
