i tried em all, don't defend the dye, if it was that easy our shop wouldnt replace stained carpet, we would just re-dye. Seriously yes its a temp solution, but in now way permanent. I rocked the dye for a year or so and I can honestly say they all suck i tried em all. I'm not just speaking blind, ive done it, and treid and tried again because I refused to have carpet with a wrinkle or bad fitment, and i finnaly gave in after fighting the dye. And honestly the only thing that held up for a long period of time was straight up Kyrlon, and eventually it wore off but its sad that wood/plastic type shit holds up better than special "dye"
