Just make sure the temp stays below 180 deg F--higher than that and you risk destroying the gel.I was working on a dead battery rescue one time (sons GF) threw a damp brass wire brush in the ammo can tool box in my wife's car. When I opened the ammo can up three months later everything was rusted.
The moral of the story is, any water that get in an ammo can stays there even in Nevada.
Here's a tip for desiccant packs; throw them in the oven at low temp for a few hours once a year* to dry them out.
*Thats for Nevada, if you live in New Jersey once a month.![]()
I use indicator desiccant to keep my hand planes and chisels dry-A few small cannisters with holes punched in the lids will absorb all the moisture getting into the storage cabinets, keeping the contents nice and dry. When the desiccant turns pink(about once every 4 months here in Fla.), I just dump the desiccant into an old converted Conair hair roller dryer overnight--when the desiccant is bright blue again(dry) I put it into sealed containers, ready for the next time. The hair dryer is just about perfect for this-holds right at 170 Degs F. Best part about the indicator desiccant is you can tell immediately when it's exhausted
