The first artist told me to give it 4 days, the second a week. I did the week, but I was tempted to pull it off earlier. My wife had her tattoo artist use the tape, but it was opaque, at least mine was clear so I could see mine.
It's what both of the artists used on my tattoos. The second artist told me to keep it on for a week. So it's all I know and even though it's a pisser pulling it off, I'm very happy with the results.
