VCI's, "active rust protection" and VP90 sachets

[Lead-Fouling]

I was just wondering if anyone had any experiences with these, in theory whilst using you it should be darn near impossible to have rust form. Has anyone used one and gotten rust?

I had the brain storm of lining my gun safe with wax impregnated with a VCI since VP90 is fairly expensive and some research (from a competitor) said it was pointless.

I've got two of them in my modest safe already.

While I was in the states some years ago I visited a gun store for the heck of it and saw something called active rust protection to which you added a fluid apparently it was a humidity, temperature and vci controller. Like a humidor for your gun

I also recently bought a browning VCI sock which makes the dubious claim of never loosing effectiveness, how can it be releasing a chemical into the atmosphere indefinitely?!

Thank you Ali for the email!



There is no shelf life on the VCI Gun Sock. The properties will still be viable long after we have departed this world.



Hope that helps-

I suspect it's simply a silicone sock and may tarnish my wood work

I use a small cloth bag filled with silica gel granules and hang it in the cabinet just as a precaution, every so often I put them on a plate in the microwave for a couple of minutes and they are good to go again.Never had a problem with any rust and cost peanuts.

I think the concern with silica gel is the possibility of overly drying the air. Not that I think there is much if any risk of that with a decent stock treatment

As suggested above a sachet of Silica Gel or if your cabinet is in an area where there may be cold, dampness or condensation then either a small heater (fish tank or vivarium) of one of the cheapo dehumidifier traps off ebay, don't buy the overpriced refills, look for bulk packs of calcium chloride dihydrate.

Interesting and certainly cost effective, again my only concern no that I've ever experienced it, is over drying.

[phaedra1106]

Unless you're going to use several kilos of silica gel or dehumidifier flakes they won't over-dry a wooden stock, all they will do is prevent some build up of excess moisture.

Hmm, I do have more than a kilo of the stuff in my largish cabinet (in a damp part of the world). Hadn't considered over-drying as a risk. I wonder if there's a cheap way to detect excessively low humidity.

Cheapish Hygrometer,

Good call on the hydrometer off ebay, I've just ordered one.

I have a nice beer monitoring setup for my fermentation (monitors and logs temperatures sends me a text message if deviates from some rules). I think I'll try a similar setup for my gun safe.

Likewise, ordered, thanks for the tip. I'm always a little suspicious of the accuracy of cheap digital stuff, but I don't suppose a high degree of accuracy is required here :)
