I am going to secure the lid of my keezer tonight to my 2x6's and I was wondering if I need weather-stripping on the top? The lid has a nice rubber seal around that seems to fit nice and flat on the top of the 2x6's, and I dont know if I can add the weather stripping later since that will add some height to the collar and possibly make the lid not be able to close toward the front. Any ideas?
