Hi Rczmk,
Yes i wrapped mine myself but it was a real pain in the butt! and wouldn't really want to do it again. If you have a go yourself make sure it's free from grease and dust etc. just a tip... when the splitter is fitted to the car you can only see 2" of it at the corners and 1" at the front near the reg plate. So what i would suggest to make the job easier is just wrap the the front 2" or so of the splitter. It would make it much easier and i don't think it would come off because the under edge of the bumper would keep it pinned down. I know it sounds a bit like doing half a job but it took me 6 hrs solid to wrap it and when i eventually fitted it to the car you can only see the front edge. Just another quick thought... you could spray the splitter with an adhesive, wrap it and wait for it to cure before fitting, but this would make the carbon wrap a permanent bond.
