Just put an air conditioner into a vinyl replacement window. There are a
few cracks and holes round it that I'd like to seal up. Looking for
something that can be easily removed since I suspect I'll take the unit out
during the winter.

Foil tape would do the job, but the wife isn't pleased with the look, so I
looking for something less conspicuous. Can anyone recommed a caulk or
sealer that doesn't shrink, but is easily removed? Or suggest an
alternative?

Thanks.
