There's a guy on SHO that just did this and he posted pics of it. He painted the floor carpet in his car and he said it works really well. He also says that it doesnt change the texture on the carpet unless you accidently glob the paint in an area. So if u do decide to do it, just take your time and be patient and post pics at the end! I'm thinking of doing this too. And about the reflectiveness of the dash, I heard that's only a problem when its painted white. Hope that helps. Goodluck
