Before rushing out and painting numbers on gutters, check that it is okay with your local council. They very well may have some rule that would make your numbers on gutters illegal - a form of grafitti or defacement of government property or some such nonesense. (If they won't allow business to erect signs - like real estate agents using pointer signs - and these are only temp, I can't see them allowing perm markings on their property.)

The last thing you want to is have to remove all the numbers you just painted.

Steve's erected signs might be the better option - looks nicer too :o)
