Nail Polish for Bullet and Primer Sealant?
« on: May 03, 2006, 05:33:52 PM »
Has anyone used nail polish for a bullet or primer sealant?

I have been looking into the subject. There are a few primer sealants available from reloading vendors. But after some reading, have found that some use nail polish to seal their cartridges.

The commonly available sealants for ammo is:



George & Roy's Custom Primer Sealant  
$8.99

All major ammunition manufacturers use primer sealant and if you want the power and reliability of factory loads, you should too, especially if you hunt or shoot in wet weather. Each 1/2 oz. bottle seals up to 1000 primers, making them watertight so moisture doesn't hinder performance.




Markron Custom Bullet and Primer Sealer
$6.99

A fast-drying easy-to-use waterproofing agent for primer pockets, bullet-case joints and black-powder nipples. It gives your cartridges unlimited storage life and is guaranteed to provide complete moisture lock-out for up to a 30-day water submersion. Will not affect pressure, velocity or accuracy, and one bottle seals up to 1,000 rounds.

Looks alot like nail polish. Nail polish is cheaper as well.

Many of the scuba divers who use powerheads made from ammo cartridges use nail polish to seal their ammo for submersion. There are a few references to using nail polish on the web. But little in the way of detailed information.

One of the advantages of using nail polish is the color selection. You can color code your bullets to visually ID different loadings.

I read an article in Shotgun News a few years ago where a guy said he uses it on all of his reloads, that's all I know.  I don't see why it wouldn't work.

Walmart sells cheap nail polish for about $1/bottle.  Get the day glo orange so you can use it as sight paint, too.  Won't match your shoes or handbag, though.  ;)

So are you saying that you have used nail polish on primers & bullets with success rbstern?

Or are you just giving fashion advice for Queer Eye for the SKS Guy?

I use nail polish for a LOT of things.  I've even used it for a sort-of threadlock compound when I raced RC cars.  Also used it to increase friction/tightness on parts-fit where I needed a tighter fit on my RC cars.

I think Nail Polish is just what the Dr. ordered here.  I would have no issues using it myself.  It forms a waterproof seal, no matter how you spin it.  And as long as the part is fairly clean, it will bond well.  No worries about chipping/peeling, as long as it's clean.

It may work well to thin it out just a little bit, then when you "drop" it into the joint between the primer/cartridge, or cartridge/bullet, it will flow well.

I tried it on one batch, just the primers.  Most of my bullets are cast lead with a wax-based lube, so the additional sealant would probably be redundant.

I thinned the polish with some mineral spirits, so it was very light.  Probably should have just used clear nail polish.  It goes on too thick in raw form.  The standard nail polish paint brush attached to the bottle cap is too clumsy for fine work.  A very fine hobby brush is better, or even better still, a fine toothepick or pin.  I didn't subject the ammo to a dunking, but I have a lot of confidence that it does seal the primer.

Used the same nail polish on a lever rifle front sight about 2 years ago.  Five hundred or more rounds later, plus a few trips to the woods, the paint on the front sight is as good as the day I put it there.

Didn't try to seal any bullets.  Don't have any reason to believe it won't work there, too.

I have used clear nail polish for this, on both ends of the cases, for about fifteen years now.

It is the best idea going for putting up waterproof ammo of the unquestionably reliable variety.

From the smell of my wife's nail polish remover, I was reading this article and guessing acetone would be the best thinner for nail polish.

There are several products on the web that are sold as nail polish thinners. I googled it, and most list their main ingredients. Butyl acetates, toluene, etc. show up often. One could probably synthesize their own from hardware store cans and avoid paying the hefty price that women shell out in the name of fasion.
