Thanks for the advice everyone... However I got bad news. I spent about 2 hours following Michael's instructions and got the darkest spots out, but overall the stripes were still looking rather brown. Anyhow I had to go run some errands and happened to pass the Mini dealership, so pulled in, figured they had to have had this issue before. Anyhow spoke to their head detailer, Service Manager and another customer who had, had the same issue. Apparently there is not bringing the stripes back from this as the San Diego sun "burns them up after a while" and the only option is to get a replacement set. Not a big deal if we didn't have the $500 3M nose bra on the car and the stickers go under it... Anyhow I guess now I am going to get in touch with a vinyl guy and get higher quality stripes that won't do this again or investigate paint shops that can paint and clear coat replacements on.
