Tito - Like Hammy said, it just depends on your collar needs and how much time you like to put into projects. Another benefit = when you lift up the lid, all of your beer lines and taps are out of the way, as you usually attach this stuff to the lid in this type of build.
I have no need for this chest freezer beside my brewing = fun project
Dgonza - The Adhesive silicone sealant (link posted above, for building small aquariums) is really easy to remove if you need to, but has a decent bonding strength. The silicone drys into a continuous strip that removes much similar to a weatherstrip, but without the sticky residue left behind. This stuff is NOT caulking, but rather an adhesive sealant. The best of both worlds, brought to you via chemistry :fro:
