I've got 5 layers of tape around my 2g plugs, but comparing them to my new stainless steal 0g plugs, I can tell that it's going to take quite a long time to get there.
Please post your experiences - I'm trying to get a frame of reference for myself. How long did it take you? How often did you add tape, and how many layers at a time did you add? How many layers, total, would you say it took you? I know everyone is different but I'd like to have at least a vague idea of how far I am from my goal :]
