Zip,
The dye I am going to use is called SEM, it uses a base color than a low gloss clear. I have researched it extensively and SEM makes the best! As far as the carpet goes, I really dont know what would work well besides just replacing it. Here is a video that shows how well the SEM works. The stuff is about $20 a can but its worth it.
