1) Everything in my garage rusts quickly and badly (table saw, tools hardware, etc.). How do I stop the rust? Garage is not heated or cooled, and is not fully sealed. Table saw has been very hard to protect, and I would like to get more woodworking tools if I can stop this problem. Details: Single car garage with utility room attached at back end, and garage and utility room attached to house on the left side. Utility room and garage share the same single pitch roof. Attic space is about 5' high at peak. We never keep cars in the garage, just tools, bikes, and storage. Neighbors have similar model house with very similar garage layout but their garage is fully drywalled sealed and they don't have the rust problems. Currently there's a 2' x 3' open access panel in the garage ceiling with no door. I assume the solution is to seal the the ceiling opening and other air gaps, and maybe run a dehumidifier. Will this probably solve the rust problem? 2) Attic space above garage will then only have 2 sources of ventilation: a triangle gable vent and a small capped stationary roof vent. Should I add soffett vents? 3) Garage attic also covers utility room, and there's no insulation above utility room ceiling. I assume I should add appropriate loose fill insulation above utility room. 4) Is it okay to use "great stuff" foam insulation to seal back and sides of electrical boxes?
