Not bad!

Wow that looks great. If you are still refusing to buy yourself a 58 cal muzzleloader, you might have to sell that mold to me!

(but the better course of action is clearly to buy yourself a muzzleloader! )

Would navel jelly work as good?

No. It won't, but do feel free to try it.

Dumb question, have you ever tried muriatic acid? Works a champ for me, especially after banging my head around with naval jelly too. Far more effective, and id be curious how it works compared to Vaporust. never had to soak anything for 6 hours in muriatic to derust anything.

Evaporust

Evaporust

Who makes this stuff ?? I'm headed to AutoZone in the morning

What's the best treatment afterwards for moulds and dies ? Our humidity is so high it's hard to keep the rust at bay

[Whiterabbit]

moisture displacing oil works best, for me. flood-spray, half-**** wipe off.

A sealed box with VCI paper.

I'm thinking about adding a larger AC to the shop to help remove the humidity

Regardless of climate and humidity, I would recommend wetting with oil and storing in an ammo can!

Keeping the mould halves from banging around is also very important. Rubber bands are useless in the presence of oil. I recommend using nylon tie-wraps to hold the blocks together.

Wow i wish i knew about this stuff a few weeks ago. I saw a bunch of old reloading stuff with rust all over at an estate auction for cheap $ and passed it over. Now i know better and am kickin myself.

The cool thing about evaporust is it doesn't damage paint. We used to use muriatic acid in motorcycle tanks, then came the neutralizing and paint damage, this stuff rinses clean.

I just ordered in another 5 gallon bucket from O'Reilly Auto Parts. Free Shipping to my door and used the "10off50" code for an additional $10 off... 5 gallons for $85.19 delivered to my doorstep. Get them while the gettin' is good.

oh yes, it does that. I tried a barrel cutoff, washing it after I stripped with via muriatic. Imagine my surprise when I came back the next day and the cutoff was bright orange! Neutralization is definitely needed with muriatic. If evaoprust is really $85 for 5 gal, sounds like it's very reasonable in price.

Yep good point

Electrolytic rust removal is king.

A quick and easy set up I have used several times:

I am told this should be done away from ones house. I'm just the messenger though.

Usually (usually) processes like this are hydrogen emitters. Hydrogen burns with an invisible flame, if not energetically. Anyone who played with MRE heaters know how low intensity the flame is. But flame it is, invisible or not, so there is a technical danger, assuming the reasoning for dis-proximity to one's home is gas discharge.

[imashooter2]

You would have to have a very large part, an unusually powerful DC source and a very tight house for the amount of hydrogen being emitted to be an issue. Yes, there is technically a risk. There is also a risk that a meteor could scream from the heavens and vaporize me in my bed. I don't spend a lot of time worrying about it though.

It might also depend on what mix your using in the Electrolytic rust removal as to what the gas is that it creates (just guessing).

The few times I tried it I used a water/washing soda mix, powered it with a low amp 12 volt car battery charger and it did bubble some but I do not know what the bubbles were.
