After 25 years of living here, and only 2 years of having a/c, I know we'll how to make swamps work, even during monsoon;). It's all about air exchange.
In this case, it'd both lower the temp but more importantly raise rh, thus extending open time.

I have this innate fear of swamps in rhee shop. Although, intellectually I know why it works and is safe, emotionally I can't get over blowing water vapor over my tools. I do have a portable A.C which seems to generate as much heat as cooling. Are not swamps large items that have to sit outside and blow in?
The current portable I have is 42" high (on it's wheels), 28" wide and 18" deep and easily pushes against a wall. It cools about 1300sq ft without having to do things like toss ice blocks in the water.
As you can see, it's not huge. It can be connected via hose, but it also has a 14gal reservoir. It generally lives behind the door. Having one that's not appropriately sized (in CFM) does make it a waste of space. After 25 years of having swamp cooled houses/shops, the only rust I have on anything came from a roof leak while my tools were in storage last year. The Rh is typically lower than anyplace on th east coast.

Mike,
Love your shop dog, ain't nothing in life as good as a good dog.
Mine was a little larger than yours but then even yours would take up too much space, Right now I'm finishing up a project in the back garden just so I have room to work, I know the real answer is to get rid of "stuff" but...

Yea, but this thing is still much more efficient, and smaller than the cooler that finally rusted out (bought in 2000 I think). Basically instead of having one cooling media, this has 3, so it's really much better by far. Eventually I'll install a cooler outside on a pad. I gotta get water plumbed out there first as I actually have the cooler. Then this will be used for the porch ;)
FWIW, you should see the other side of the shop right now. I'm still just moving things around to make space to work (and still working on getting insulation installed).
I'd contemplate a mini-split, but to do that I'd need to add another service entrance, and I really do not want to go there.
