i read somewhere if you put some painters tape over top the sticker, then use a box cutter to trim to about same size you can slowly peel it off with the painters tape helping to keep it all in one piece. then you can easily place it on something else (under seat).
The process is simple, but the execution demands great care (at least for me):
1. Gather materials: 1 roll of blue painter's tape, a ruler or tape measure, pencil, scissors, tweezers and hair drier.
2. Measure the dimensions of the sticker to be liberated. Some stickers will require 2 overlapping tapes to be wide enough.
3. Draw outline of sticker on painter's tape and cut.
4. Carefully place tape on sticker, making sure the edges are covered and tape is tightly & smoothly pressed on.
5. Apply copious amounts of heat. If you think it's hot enough, apply a little more.
6. Choose a convenient corner to work from and carefully start to peel with tweezers.
7. Once enough edge is exposed, grab with both hands and peel. Keep applying heat as necessary.
8. Once liberated, transfer to new real estate under seat.
9. Clean-up excess glue on frame with WD40.
Good luck!
