Outer Limits 4x4 Board

now i have a gal tool box that i may as well use as my own coffin on the back of my 75 ute.

Now i have have carpeted the inside of the tool bob on the bottom and on the sides but not the lid.

I am sick and %$#*&^@ of opening the tool box when needing something to find that everything is drenched due to condensation.

I have sealed all off the gaps with no more gaps but cant work out why it is doing so, a few of us stood around scratching our heads and came up with that it is warmer in the box then outside thats why its condensating.

Any help would be heaps good will try most things to fix it, its driving me bannanas thanks guys.

Run a length of heat resistant hose, (Air hose or heater hose) From the radiator fan shroud to the box. If you're in a colder area, run it over heat shield on the exhaust manifold (use a length of copper tube as a heat sink if you need it)
1/2 inch or 5/8 inch hose should be plenty.
You'll need to have an outlet from the box too.
The fan should force enough warm dry-ish air through the box and get rid of the condensation.

Maybe it needs venting?

Tried the dessicants (sp?) that are supposed to go in bathrooms and the like?

go to hardware store and buy a couple of brick vents and let it breath

The prob is because you have sealed it up, the air trapped in there is already constantly moist.

Try

Emptying it, drying it out all weekend,

then put the vents in to let it breathe.

The condensation is from the cold air outside chilling the case and the water cooling from the moist air inside on the inside of the case.

Park it under cover, put in vents.

You won't win this one though, you are always going to have an amount of condensation. Try leaving it open as much as you can throughout the day.

yep I agree with above.

You need to put some air vents into it.
Get some wall or brick vents. (ones that are angled down - so water cant get it)

The carpet will hold moisture as well. Maybe a bit of rubber would be a better option.

my tool box has unsealed seams, a couple of holes in one end and a loose fitted lid.
Ive never had moisture problems with it.

But I have seen your problem before....

Agree with the air vents, with an added option. If its permenantly mounted, rip apart an old computer and grab a 12V computer fan. Mount this inside one of the vents, so it positively ventilates the toolbox.

Good idea, but warm air can sustain a higher concentration of moisture in it, so you may be introducing more moisture into the cavity. The condensation will be worse as the air cools down and the vapourised water condenses on the internal surfaces.
