I am about to do a harlequin wrap on my son's road bike and want to make it as nice and durable as I can.

Will any ole' shellac do? Is there a brand/type that is better than others? Is there anything else I should be aware of going into this for the first time?

As a side note has anyone ever seen or themselves wrapped non-aero levers with twine?
