Engine build storage questions

Hi all, I was talking with another member here who is in a similar climate as myself in Ontario.
We're both in the middle of an engine build, altho mine has "stalled" but I plan on getting back to it over the winter.
Should there be any concern of humidity/moisture/condensation/rust throughout winter and spring?
My garage can be heated, but I dont run heat in it 24/7. I would turn it on prior to going out to shop and turning off after a few hours or so.
Thanks
I got my engine back from the machine shop in the dead of winter 2 years ago. I sprayed the crap out of it with fluid film and wrapped it up tight with a roll of plastic wrap and it was good for a month while I waited for stroker kit. RJ
