Outdoor storage – Jointer

Background: I bought a used General International Jointer in the summer of 2017. I don’t have room to keep this inside my shop. The surface around the shop is gravel which makes it very hard to roll anything around. I decided to keep the jointer permanently outside and do the best I can to prevent damage from the elements. I live in the Sierra Nevada foothills of California. We can have lots of rain for about six months but very little snow. Summers can get up to 100 degrees.

I’ll document my experience here and hopefully it will be helpful to someone.


On August 18, I received a Montana Grill Cover and immediately put it to use on the jointer.

The weather was warm and rain free until around Oct 19. We had some rain early morning Oct 20. I checked on the cover and saw some water standing on the exterior. Later that day, I uncovered the jointer and was heartbroken to see the previously shiny cast iron surfaces were covered in orange rust. There was some water sitting on the outfeed table and beaded water on the cutting head/blades. Since the cover is waterproof I concluded the water was from condensation.

I had to leave early the next morning, so I spent a few minutes applying WD-40 and sanding with 600 grit waterproof sandpaper. This got some of the rust off. I sprayed the infeed and outfeed tables, cutting head and fence liberally with WD-40 and re-covered the jointer.

On October 30 (9 days later) I returned to the project. I found the surfaces just as I left them, rusty and damp with the WD-40. The rust did not advance. I used paper towels soaked in paint thinner to get as much of the rust off as I could.

The pictures below show the jointer just after I did the above preliminary cleaning. It actually looks way better than when I first uncovered it 9 days earlier. Looks like the WD-40 prevented new rust and also helped dissolve what was there.

The next step was to apply “Rust Free” by BOESHIELD. I sprayed it on and scrubbed with a scoth brite pad. It worked great and removed all the rust. There was a residue from the Rust Free product that I tried to remove with paint thinner. That didn’t work well, so I just resprayed Rust Free and immediately wiped it off. That took most of the residue off. The pictures below show the shiny surfaces are once again shiny and rust free.

I decided to use two products to protect from further rust. On the left side (outfeed table), I applied RIG Universal Gun Grease. I also applied the Universal Gun Grease on the cutter head/knives and the fence. On the right side (infeed table) I applied BOESHIELD T-9 Rust and Corrostion protection Waterproof Lubrication.

The Gun grease was simple to apply – just rub it on and leave it. The Boeshield T-9 said to spray it on and let it dry. I waited about 45 minutes and it never dried, so I wiped off the excess which left the surface still wet. I re-covered. I’ll check after I return from vacation in mid-november to see how it looks.


19 days later and lots of rain … I uncovered the jointer to find that the grease and Boeshield had both done a good, but not perfect, job of protecting the shiny surfaces from rust. There were beads of water (from condensation I think) sitting on those surfaces. As you can see from the pictures, the Boeshield T-9 did a better job.


I placed a nightlight with a 4 watt bulb under the cover. It’s located near the cutters. I’m hoping that will raise the temperature a bit and stop the condensation.

I checked the temperature at about 7:30 AM on 11/28. It was 40 degrees both outside the cover and inside the cover on the infeed table. Looks like 4 watts is not enough.


The rust on the side protected by the Universal Gun Grease advanced a lot as you can see from the pictures. The side protected by Boeshield looks the same as 11 days ago. Boeshield T-9 is clearly the winner. I used paint thinner to remove all the grease and followed up with Super clean Degreaser. After that I used Boeshield Rust Free to remove all the rust. I then sprayed Boeshield T-9 Rust and Corrosion Protection Waterproof lubrication on all the shiny surfaces and some of the painted surfaces too. I let it dry for a couple hours and it was still wet (the temperature was in the 50s). I left it wet and replaced the 4 watt nightlight with a 25 watt shop light and covered it with the waterproof grill cover.

12/1/2017 8 AM

I measured the temperature outside and inside the cover on the infeed table: 44.6, and 46.7. The 25 watt bulb is making it 2 degrees warmer inside. The outside of the cover, where it is touching the bulb enclosure felt warm to my hand.


We haven’t had any rain lately and temperature has been in the 40s at night and 60s during the day. I checked under the cover and found that the Boeshield T-9 never dried and there was some rust blooming on the outfeed table. I used Boeshield Rust Free to clean that up and put a fresh spray of Boeshield T-9 on all the shiny parts. This time, I wiped off the excess. I also noted there was no water condensation present. It could be that the 25 watt light is helping or it might be the mild dry weather. I didn’t like the cover making direct contact with the metal shroud of the shop light, so I modified a plastic box to cover it.

If that is you only place to keep it I would build a sealed cabinet around it and put a dehumidifier in there. That is “raw” steel on those tables and will be almost impossible to keep it free of rust under those conditions.
Maybe a coat of cosmoline…..
You might see if a plating shop will Chrome plate the tables for you.

The tables are cast iron, not steel.

But the point stands. I would never store a jointer outside. Is there really no way you can cram it into your shop space?

It really needs a home inside, permanently and dehumidify for all cast iron machinery. T9 is a great product, but has its limit to outside exposure. A great need is expand your shop area, ASAP!
Good wishes.

Just an FYI – “Rust Free” is just an expensive dilute phosphoric acid with a little bit of alcohol mixed in to give it that pleasing smell :) And T-9 is an expensive mix of mineral spirits and paraffin wax with a little bit of mineral oil thrown in for good measure (which is why it takes so long to dry). You can get a dilute phosphoric acid and a can of paste wax at the BORG cheaper and it will last you 10 times longer.

If you want to keep the tables rust free, you need to isolate them from the moisture… the key ingredient in those and other ‘rust preventers’ is wax, and Johnsons paste wax (paraffin, caranuba and microcrystline in naptha) is the go to standard. A few good coats of paste wax, then covered with cardboard, plywood or something similar will do that easily and keep the tables rust free.

Thanks everyone for your interest and comments.

I should add for the benefit of anyone out there who is thinking about storing a jointer outdoors…. I do not recommend it. You should keep it indoors. Some would say it’s a violation of common sense or even common decency to treat a tool as I’m doing here. Since my other options are all very time consuming and/or expensive I’ve decided to store it outdoors and do my best to prevent and to deal with the resulting damage. By documenting this, I hope to give others the benefit of what I’m learning as I go.

Jonah asked if I really don’t have room to keep it indoors. Well, I do have room to store it indoors. Unfortunately, my workshop used to be an office. It has regular man doors with high thresholds. To make matters worse, the area surrounding it is covered with gravel. If I had wheels on the jointer, I’d have to make a concrete path to roll it on and modify the door threshold so that I could roll it in and out.

Mr. Unix: Thanks for the chemistry lesson. I did put some automotive type wax on it before I tried anything else and it didn’t seem to help at all at preventing rust. Maybe I’ll try Johnson Paste Wax on one side and Boeshield T-9 on the other.

Les B: I am thinking about making a sealed cabinet and adding a humidifier. That will probably be next summer though. For now I’ll carry on with removing rust as needed. If anyone has details on such a cabinet, please point me in the right direction. I’m dreaming about a cabinet I can easily slide out of the way or just lift up and off the jointer.

Dan: Thanks for the encouragement about expanding my shop area. My wife says the same thing. I think I should live with what I have for a while. We moved to our present home about two years ago and now are mostly retired so I’ve decided to take my woodworking skills to a higher level.

Looking at the bright side of things.With all the oil ,grease and wax you have on the jointer beds your wood will almost have its finish.:)

Try spray shellac to seal the cast iron. Found that tip here in several threads and did it with my table saw. I don’t have standing water, but it’s in the garage which has periods of extreme cold and humidity and haven’t had any problems with rust.

Otherwise, you need a roof over that. Build a shed. Or maybe a temp structure like one of those instant garage tents.

Have your say...
