I can’t speak to salty air, my tool storage is in a “shed” at the back of my carport. The soffits and the top of the “interior” wall from the soffit line to the roof peak are open to air flow. I’ve contemplated what it would take to button it up and install some sort of exterior door (and run a dehumidifier) but I don’t know if the reward to effort/cost ratio is worth it. I live in Eastern Washington, just south of Seattle and we get Rain in the Fall though the spring (moved to WA from NH for a job change, a 3000 mile cross country move was not fun or easy).

The last 2 years, my TS and RAS were stored in a shed built on the side of our house, and the temperature and humidify was fairly constant and I didn’t see much rust form. This is the first year I’ve started to do any woodworking and have been storing my TS, RAS, and Jointer in the carport shed since mid-summer (a friend of mine wanted to do a project so I moved them all into the carport storage area).

I’m contemplating covering my TS and jointer with a good coat of paste wax once I finish my current project and put the tools into storage for the winter. My smaller hand tools are stored indoors in my utility room.

I’ve read that, as others suggested, Boeshield T-9, Paste wax, and for tabletops (like a table saw), simply building a wood box to cover the top (not the whole saw) can help reduce rust formation. I’m going to try paste wax and a box. I may try to get some silica gel to see how that works too.

I did read on the back of the Boeshield that re-application (on the aerosol can) is every 2-3 weeks. You can coat it thick and let it dry, it dries tacky. Even then it needs to be re-applied periodically.

Don’t, I repeat, don’t use WD-40. WD-40 (so I’ve read) can actually trap moisture near the metal and cause rust to form.
