Some degenerate left gum on leg of a chair and it suck to back calf of my pbjs. I got the gum off, but the gum took a lot of the indigo out and left a solid fade mark. If this was my thigh or something I'd probably wabi sabi and let the fade even out, but the back of the calf is a spot that fades minimally. I'm thinking of buying this dye off amazon to cover up the fade mark, any other suggestions?
