SmeezeKitty, do as you wish.
All I can tell you is that I had to replace every rubber hose on a diesel engine because some lugnut sprayed them with the same 'Perkins blue' as the rest of the engine. And to do that, we got to lift the engine out of the boat, drain it of all fluids, etc. Not the fastest fix.
Every hose had cracked thanks to this painting treatment. Given how important belts are, I wouldn't mess with them and pick up the desired signal elsewhere.
