  1. 1

    Purchase a car dent remover suction cup or other industrial quality suction cup.

  2. 2

    Cut away the built in rubber handle with a razor blade. You should only have the cup left when you are finished. Be careful not to puncture the cup.

  3. 3

    Take off any residue left by the rubber handle with your razor.

  4. 4

    Place the suction cup's back against the plastic frame of the old suction cup; note where the new suction cup would connect to the old frame's adhesive plate. Draw a line around the perimeter of that connection with a permanent marker.

  5. 5

    Cut around the line drawn by the marker with scissors. The line delineates the ideal circumference of the suction cup. Cut away all excess circumferences.

  6. 6

    Use rubber-to-rubber glue to adhere the new suction cup to the old frame. Let dry for 24 hours before use.
