rusty toolbox

[Aernan]

After some rain my toolbox is now wet inside. I did notice that it is rusting quite a bit. I see in the top left hand corner there is a small vent hole. Has anyone tackled this repair yet?

I have a good one here. Shipping to Cali isnt cheap though.

I think I just need to rust convert it and paint the interior. I'm looking at plastic mats to keep the contents dry when it leaks a bit.

When water gets under the mats, you do not notice it until to late.

I cleaned mine out really good and repainted the inside. I found that the door seal was worn out on mine and that was where my water got in. I also just left my bottom steel with no mat. I want to see it and not let the moisture hide.

I remember on some car seeing a drain that looked like a funnel mad out of rubber with a pinch point. If I can figure out who makes them I will add one to make the box drain.

Duck bill drain

yeah that's it exactly! Thanks.

I was also thinking about enlarging and replacing the hole with a "pressure compensating device"
something like

We use them on our products to normalize the air pressure but not let water in/out.

Maybe when I build the camper on the box I'll run a spare air line to the toolbox to force any built up water out of the "duck bill valve". I have heard that positive pressure on all boxes is a good idea when fording.

Unicat uses air in there storage compartments to keep water out of them. There is a you tube video where they talk about it. I used to pressure test compartments on Navy ships, testing for water tight integrity. Most would be very surprised at how little pressure you need. Just volume required. A ships compartment that is 10 foot x 10 foot x 8 foot can't exceed 8 psi (by maintenance instruction), or you risk blowing out bulkhead fittings, buckle the bulkheads (walls), and or buckle the water tight doors. So it wouldn't take much to do these storage compartments. Just need to control the pressure and allow for a vent. Our compressors will have the volume capacity I'm sure.

On fire trucks, ambulances and on my MV's we use deck mat/ dry deck keeps an air space between the box and tools , this is just one of many types http://www.americanfloormats.com/duragrid-deck-matting/ https://alliedproductsllc.com/product/dri-dek-floor/
