Magnetic and rubber weatherstripping should both work on exterior steel door

And which is the more effective weatherstripping? Madge C. Hall Westfield Center, OhioSkip to next paragraph

A. One Lumber dealer says he has the magnetic-type weatherstripping -- mohair, not vinyl -- on five of his exterior metal doors, and reports no paint flaking in three years.
Perhaps someone else faults the magnetic-type stripping from a different experience. In any event, the problem ought to be minimal, even if flaking does occur after a time.
Magnetic weatherstripping would probably last longer than rubber in a hot, dry climate like the American Southwest.
