Clear silicone caulk is designed to go on top of the finish coat. That's why it is clear. There maybe an application in which silicone caulk is appropriate, I have never found one, and the exterior of a house is definitely
the wrong place for it. Seeing that it is done, the easiest way to make it paintable is to hit it with a spray bomb, and then put your latex finish coats on top of that. I would however be tempted to remove it altogether and redo it with something better as I don't consider silicone to be durable. If you do remove it, you will learn the other reason why it is a devil to work with.
