So I took the plunge and ordered a helmet from Sure Shot this morning. Going to New England Picture tomorrow (Manchester NH) to look at their cases even though the ones on their site aren't exciting. I saw some nice ones online with a laser etched pats logo and a mirrored back, kind of hoping they have something similar.
Anyway, aside from putting it in a case to minimize the number of hands touching it, what else should/can I do to make the signature last without altering the appearance of the helmet or causing it to become worthless overnight?
