Here is a tip for another thing NOT to do. I used to carry a waterproof .50 cal ammo can in the boat. I carried tools, repair items, paperwork and such in it. I also stuck a can of bug spray in there, Off I think it was. One day I went in to the boat lot and there was a lid of a ammo can about 30 ft from the boat. It was bent up some. I went to the boat and found a very bent ammo box and a bunch of rusted and ruined stuff scattered about. The spary can had blown open the sealed ammo can. Conclusions: 1. I wish I had been around to have heard it go off. 2. I'm glad I wasn't in the boat when it did. 3. I don't use spray bug stuff anymore, I use liquid. 4. The liquid will also leak out and eat anything plastic, put it inside of 2 zip-lock bags.
