I have a call in on this but thought I would ask meantime. I ordered some Copper colored acid dye. Just mixed it up following the instructions. The color looked OK but soft of dark in the pot. Tried it on a scrap piece of the nylon and it was anything but copper. It had a green cast to it. Dried it with a heat gun and it looked better, not good! It was a muddy color. No where near the reddish copper I was expecting. I put some poly on it to make sure and was not impressed at all.

I finally poured it out. No way was that going on my boat. Anyone had anything like this happen? I kept thinking I did something wrong but I measured out the water and vinegar and sure I got that right. So I have to assume the mixture just wasn't copper.
