Why does my Personal Survival kit need to be waterproof? People find themselves in a survival situation by unforeseen events. Usually those events being bad...We do not decide or predict when and if this happens; but your Personal Survival kit is there waiting to aid you. Your gear isn't going to help you if its been destroyed.
Obviously a tin alone is not waterproof. In many discussions I've had people say they waterproof their Tin based survival kit with some sort of tape (most of the time being electrical tape). So we tested this by wrapping electrical tape around the Altoids Tin and submerging it.
So after taking the tin out of water and removing the tape; the tin was completely filled with water. Just as if I had not added any tape at all. I'm sure the tape slowed it down but did not make the kit waterproof.

So you may or may not care if your kit is waterproof. Although, I would suggest against that thought process. But if you must use a tin, at least waterproof everything in your kit that could be damaged by water. Again I'm not bashing Altoids Tin's. But hopefully provide you guys with the best information in building your own PSK's.
