Having completed my CLC 17 LT kayak, I applied for state of Illinois watercraft registration (only $13. for three years). But now I have to attach the HIN (hull identification number) that they issued. According to the regulations, I must either "...carve, burn, stamp, emboss, or otherwise permanently affix the HIN to the outermost starboard side at the stern...in such a way that alteration, removal, or replacement would be obvious and evident." (There are 12 characters total, and they must be at least 1/4 inch in height).

Any good ideas on how to do this?

Thanks, Ed
