I wouldn't use the rubber mats as they will collect moisture between the mat and the safe. Again, make sure the garage is sealed as well as can be. Make sure the bottom seal of the door is good and you might want to see if you have room to install felt, rubber, or foam gasket around the door. I don't care for the foam as much because unless it's compressed, it will still allow air and moisture to get through it.dawgfishboy wrote:The largest GoldenRod thal will fit and a handful of Eva-dry's will take care of any humidity issues.
And no, I don't think you should tape over any door seams:SourceHow does GoldenRod® work?
GoldenRod® heats to a surface temperature of less than 150 degrees (which is almost too warm to hold) and circulates warm, dry air throughout an enclosure on a 24 hour basis. This increases the temperature of the air inside to several degrees above the ambient outside temperature. Expansion of the heated air forces the moist air outside through the vents or loose fitting doors leaving the dry air inside. In order to work correctly, it is important to ensure that there is adequate ventilation.
Bolt it down good and build a cabinet around it for concealment.
Maybe keep it off the concrete with a rubber mat or metal spacers if you're concerned about rusting the bottom of your safe. I used these and my buddy used something like this.
Or you could put a separate a/c and heat system in the garage. This would allow you to maintain a constant temp for working out there. I had to do this since our laundry room was in the garage and my wife always complained it was too hot or cold. After I installed it, I was able to work on my bike out there in comfort as well
