  7. If seal strips have already been installed here, you’ll need to remove the old strip and any residue to install the new seal strip. To do this, use a putty knife, flathead screwdriver, or your fingernail to lift the corner of the strips and peel them off.
    Removing old seal strips and residue
    1. You can also use ⅜-inch (9.5 mm) strips of sturdy duct tape. Apply tape to residue, rub to adhere firmly, and pull off. Repeat around the port. Clean any residue left behind with rubbing alcohol.

    Applying the first seal strip
  9. Repeat the process for the second seal strip: Remove the adhesive backing and place the strip on the right side of the globe entrance. Again, the strip should be placed toward the front edge of the globe lip.
