Old timer in Detroit showed me this trick with door magnets
Guy had been installing since the 80s, told me to put a tiny piece of tape on the magnet face so it doesn't stick so hard to the contact - stops false alarms when doors slam shut. Has anyone else tried this or is it just an old school thing?
Tape degrades over time, so the real fix is a dab of super glue or a tiny screw if the magnet's loose. Once that tape hardens or peels, you're back to false alarms anyway.
