How to put a License Number on a Boat?

[cgb]

I just received my pleasure craft Licence number. According to the approval, I am required to write in block letters 75 mm high the number on each side of the bow of the boat.

I'm curious how people have done this in the past? Does anyone sell peel and stick numbers/letters for this task? I checked Canadian Tire, and the best I could find was house numbers, but there were no letters.

Michaels has letters/numbers, but I don't think they would be water proof (I'm not sure).

Thank you
