Primer sealant?

[bullseye308]

I was thinking about getting some nail polish to use as primer sealant for long term storage. I may get different colors to keep different loads separate also. How is it used, before or after seating the primer?

After. If you use it before you seat it won't seal the primer.

You might need a little acetone to thin it out.

loctite works well too. just one drop and rotate the shell it will go around the primer

loctite works well too

Only if it can wick in.

Loctite is an anaerobic adhesive.
It hardens in the absence of oxygen.

It's really not necessary in the first place.

Put your long-term storage ammo in a good GI ammo can and don't worry about it. Moisture can't get through the lid seal.

The problem with painting primers after they are loaded is, all that paint flaks of inside the gun when you shoot it. Then it gets in the firing pin channel, and other places it shouldn't be.

Factory ammo with sealed primers has the lacquer applied when the primer is seated.

If you want to mark different loads, use different colored Magic-Markers.

i agree with rcm. a while back i did some ammo soaking and never found a single time where the sealant made a bit of difference.

Years ago,after a "groundhog outing",I forgot about three .223 rounds (no primer sealant) that were in the pocket of my shorts.They went through the Maytag cycle & they "went bang" when I wanted them to.I'd not suggest counting on rounds after going through that,but I've not worried about sealant since.
Were I in situations where I'd potentially have my rounds under water,I'd use a sealant.
