Is a mobile evaporative cooler in a tin shed a bad idea?
My existing ceiling, wall and monster floor fans just move hot summer air around with only moderate cooling effect.
A mobile evaporative cooler would be much better when I can point it where I'm working.
What I'm concerned about is whether this is going to promote rust on tools and machinery. Rust on the shed frame isn't an issue as it's fully galvanised while the cladding is coated both sides, although there's the possibility of condensation on the metal. That's probably not a major issue as usually I'd be using the cooler only while the sun is heating the shed and for maybe half an hour afterwards, but perhaps longer on unusually hot days.
Any opinions and especially practical experience welcomed.
