The stickers CAN be removed - but it's not quick. Using info located on other forums, people were saying that 90% isopropol alcohol would remove the "bonded" type stickers that we have on the SSRs. Well, all I had was 70% that I had on hand. I removed the driver's side visor and saturated a cotton ball with the alcohol and started rubbing it on the sticker. For several seconds, nothing was happening. Then I noticed that the yellow ink on the sticker was starting to smear and the sticker looked like it was getting "soft". I picked at it with my fingernail and the sticker peeled off only where I picked at it. Well, now I was commited - that visor wasn't going back on the SSR like that!! I just kept wetting the sticker with alcohol, and gently picked it off with my fingernail. Took about 20 minutes. After all the sticker was off, I gave it a final scrub with alcohol, and then liquid soap and water. To restore some moisture to the vinyl, I applied Armorall (Don't believe the wive's tales - but that is another story!). It was perfect! (O.K. - ALMOST perfect). At the right angle you could see the rectangular imprint of the sticker as an indentation in the vinyl. I used a hairdryer at that point to get the vinyl very warm to the touch, and voila' - no imprint. I repeated the process for the other visor and they both look like they never had a sticker on them at all!
This is not at all difficult, but it will test your patience. You must remove the visor to do this (3 phillips screws and a wire dis-connect). As I mentioned, the end result are visors that look as though they were manufactured without the stickers - VERY NICE. (Just don't call the "sticker police" on me please!)
