I have a wicker set of furniture that I've had inside for a while, but now I'm getting new furniture and want to put the wicker outside for some patio furniture. Is there something special I should be putting on it, like a spray or something, or will it be okay in the elements? I'm in Alberta, Canada and we get rain, snow, hail, etc. Bringing the furniture inside on a crappy day isn't an option. Any help would be appreciated!
