Try some Jasco paint remover on the underbody paint.
From my experience, it reacts with the top layer and leaves the next layer down pretty strong.
I would put it on and walk away until it dries. If you try wiping off when wet there will still be active remover and it will chew on the schutz stuff.
I don't think this is a common procedure. I am assuming you want as much "factory" to remain on the car as possible. I like the spirit but I like just painting the same paint over the factory underbody paint in close to the same intensity. You are aware it varies.
I do know that the base black/dark gray primer is absolutely bad ass. You cannot cut it with the JASCO. There is a valid argument for stripping the top layers if the factory primer is impervious to the stuff. Stripping is so damned clean.
I stripped my driver's rear quarter only. That is my statistical mass of experience. The black primer was on that panel.
