I was wondering about crevice corrosion when I responded too.
An option for really large shrink tube, is plastic bottles. Anything that is made of the same plastic that 2 liter pop bottles are made of (PET, nearly all stiff clear plastic, and virtually all beverage bottles) will shrink when heated. So will many other types, but that plastic is so widely used that I always grab that type rather than experiment with others if I need to wrap something.
Many uses for that on a boat or in a car. Can make light duty brackets by either shrinking it around what you want to hold, or carving a form from wood and shrinking it. Also have made adapters for round to square ducts by carving the required shape and shrinking a 2 liter around it.
