Have you looked into spray paint?

Hello Ian -

Some folks here in the states are vain enough to get their six pack spray painted on - hey, it looks good for a while and it works for the movies. Since you didn't give a duration for how long they had to last - check into it!

Don't know if I could quite call the goal achieved if I did this!!
