What is best to seal leather after dying it? How do apply it without taking the dye off? I think I just ruined a project I was working on for a customer when I was sealing it and it started removing a lot of the black dye. I am about to throw in the towel doing leather work if I cannot dye it and the dye stays on when I seal it. I was spraying super sheen but it had a lot of bubbles and I used a sponge to try to spread it out to get rid of the bubbles. Last time I sprayed it left spots where the bubbles were.
