i have a one car garage with concrete floor, cinder block walls with a flat roof that is not insulated. the garage door is new but no insulation. I use propane for heat. it seems that at the end next to the big door my metal table top are rusting and have moisture on them. I was going to put foam board in the garage door panels, its damp in the summer it seem like but this is a bad problem for me any suggestion

This is an age old problem,we all suffer from it.First of all your propane heater will be producing most of the condensation,if you could change it to electric or oil filled radiators things should improve,your breath causes a lot as well but you can't stop breathing,fit a Vent Axia or similar to draw the moisture out of the building or invest in a small de-humidifier.In the short term leave all doors and windows open for 30mins or so when you have finished working to allow the warm damp air to waft out.Insulate the roof first as this is where it drips down from when you leave(doesn't matter if it runs down the wall).
