How much money do you mind spending?
How much time do you want to spend?
How nice of a result do you want?
What covering material do you want to use?
If the answer is "not much", "not much", "not much", and "Monocoat", then get some vinyl stick-on lettering at your local craft store.
If the answer is "as much as needed", "as much as needed", "perfect", and "paint (or dope) topcoat", then get someone to cut you out some masks and spray the lettering on.
If the answer is somewhere in between -- let us know more. I think there's a chance that you'll get some opinions.
