Hi,
I carry alcohol in my checked in luggage in a small bottle,disguised as something else,.I have never had anyone check what i carried in the bottle,even though they say you can't carry alcohol.

I would do your trip without removing your piece,maybe do a trial run (ie 15 days)before you go away to see what its like to clean up after a long period,you could try heavier tapes that don't break down as easy.To have a spare piece lying aroung with supplies on holiday is going to be hard to conceal.

Been through airport scanners with a piece on,never had a problem.
