The Stickers were the first thing that had to go.
In case it came out badly, I had a matching slip over sun glasses/pen/paper holder to cover the visor.
Trying to peel the sticker DOES NOT work.
The sticker brakes apart as you pull it.
The best you can hope for is to peel a 1/4 inch section along the length (left to right). The peel usually breaks after 1/2 - 3/4 inch section. Then you must start the procedure over, and over again. Start the peeling with a sharp razor blade, and don't cut into the fabric.
When finished the passenger side (done first) had these light "Paste/Glue" lines where the sticker was. The paste does blend in slightly with the light grey visors, and is not completely rejectionable.
With this being "OK", I proceeded to do the drivers side hopping to repeat the same results. Unfortunately
, the drivers side visor had three (3) holes under the sticker. I was careful in not making these holes, and am sure that these were in the visor prior to the sticker. I guess in Mexico, if you cover the defect, there is no defect.
Anyway, Good Luck in removing the stickers. Maybe someone will make a matching sleeve that fits over the visor (and leaves the mirror open).
