Got this from a fellow forum member years ago, but boat was sold before I stuck it on.
Unfortunately it got some Awlgrip Ocean Mist overspray on it, while it was in my toolbox, but it is still perfectly legible.
Its an "aluminum-ish" like sticker, and you might be able to get the overspray off with acetone or something. But I haven't tried.
Happy to put it in an envelope for someone with an 18 footer.
