carpet dyeing free carpet for duster

Penstarpurist said
I met a guy from a craigslist ad locally in my area that was advertising several different parts for a 73 duster. So I bought a few parts and he asked me if I wanted the original carpet from his car that he had replaced and kept the old one. Our 400bb duster project has no carpet in it and the used carpet was in great shape but gold in color. So I bought 3 boxes of ritt dye and a cheap new large garbage can. Filled it with hot as heck water and stuffed it in there. I know there are threads on here of guys using spray bottles or rattle canning. But figured since it's already out, and the directions said fill a bucket and submerg. I'll let you know how it goes. I'm letting it sit all night in it. Saw a guy on YouTube do it this way with good results.

Good luck with your project. I tried to do a set of floor mats. 2 days soaking in the tubs. went from grey to umm wet grey.

If it's a synthetic carpet (80-20 loop or cut pile) then the content of the carpet is rayon and nylon. Dye just won't bond well.
We use a water based spray dye that has a cross linker chemical that bonds to the fibers (makes em a little bit crunchy though) and even that is just for minor touch ups an will not last long with any kind of use and best for seldom touched carpet. the cross linker and color solution works pretty well on Vinyl and rubber but struggles with carpet synthetic's.
