I have mine going through the stock relay as well--no problems.

The bare metal of the horn needs to be connected to the engine chassis for grounding purposes. If you painted over all the surfaces you're going to have a very high resistance circuit and the horn will not work. Clean off the paint where the bracket connects to the frame and try again.
