Unheated shop rust prevention

CRC makes a spray on protective coating (SP-400) that I have been using on stuff as a clean it up and it seems to be working good. I'm cleaning stuff then spray it down. move on. So far it has worked. then just wipe it down when I start working and lightly spray down again afterwards.

I feel your pain SKREWD. Even with the machines covered this is what I had last time it hit -27C (-20F) here on the North shore of Lake Ontario. I can have the wood-stove going all day and it won't help much with these temps; shop's a bit breezy. Definitely going to try that Fluid Film idea, F350ca; I've seen it in stores, thanks for the info. Wouldn't want to put your tongue on that Anvil, eh?

The only real answer is to always have the shop temperature above the dew point. Here that happens pretty much naturally. In northern and humid climates, you will need to heat above the dew point, or lower the dew point by removing the moisture, or do both. Rust inhibitors can only do so much for so long, water and rust always win.
 
All that frost makes me shiver. I luckily heat the shop and house with a wood fired boiler so I don't have those issues in the winter. Summer is another story, the machine shop stays at about 17 C all summer. If I open the big doors on hot humid days the tools are all covered in literately a 1/4 inch of water. Wipe and oil time.

okay orderd Boeshield can which I have used before on my Barrett but I need the spray can version this time.

I wasn’t thinking out side the box, I cover everything in plastic. Was going to double cover with a tarp but an building inside a building, why didn’t I consider that. Far easier, quick and when I make another “man cavern”, I can make it a tack room.
 
Did Amazon today and The Home Depot tomorrow, thanks great suggestions, I am using them all, sprays ,two walls and a door, insulation, tyvex roll, space heater. This will work, thanks again.
 
Dow Corning Molykote Rust Prevention Film is the longest lasting product I've used to date. Fluid Film needs to be reapplied every year or so, depending on use. ( I use it on the underside of my cars, NY winters and all). It smells terrible for a few weeks. A dehumidifier will also go a long way at keeping rust at bay. Small hand tools? I keep them wrapped in Zero Rust CorTec Vci paper. Works great. Machines; A bit more difficult, where you can't really get to all parts of the machine. Without a temp/Humidity controlled room, the rust battle gets very difficult. Meticulous maintenance and cleaning/oiling may be your only bet. There's a great book called "

I bought some Armor type MPI VPI paper on eBay and put it in with many of my tools. It works. Make sure the grade of VPI you get is appropriate for the material and conditions you are working with. The Armor VCI paper is also coated on both sides.

The 30G that is currently being sold on eBay is also good for ferrous metals:

Store the VPI in an air tight container so it is still good when you need it.
