I fear that your problem is the salt air, but consider that good ventilation may be the most important thing. When my shop was in my garage I had condensation problems on my TS. I believe this was caused when my saw cooled off at night then stayed cool while the air warmed. Cool things in warm air have water condense on them. What you need to do is try to keep your tools the same temperature as the air. How to do that…
