Water Sealing A Tote

Hey guys, wondering how everybody seals their totes around the lid? I have smaller totes that work fine like this but shorter http://walmart.ca/details?assetId=47592&fromSearch=true no problems. Its the bigger totes like this http://walmart.ca/details?assetId=48864&fromSearch=true is where I am having the problem, its around the lid. I was thinking about weatherstripping but the water would just erode it, and silicone would seal it shut and I dont want that. I need to get in and out but still keep a seal where no water will seep out. Ideas?

I use weather stripping. The rubber stuff not the foam. For my big totes I use weatherstripping and spring clamps.

You can see the clamps in the bottom of this pic

Thanks dude, I was checking out the rubber weatherstripping and there was a few different ones, which do you recommend?
