The manufacturer says:

Ensure all surfaces are clean, dry, and free from any previous finish. Sand the substrate with a fine 150 grade sanding paper or 150 grit sanding disk, removing all traces of dust.

They know their product - not sure why you'd do anything but what they recommend.

Don't plan to, just wanted to ask the question to people who may have tried

Do you have scrap similar to what you are working with? Do a set of test grit/finish combos and you'll have your answer.

I wish but no. I'm going to follow the directions, but this has been good for understanding why

All finish products need some kind of roughness to adhere to / into.

If its too smooth, the pores (think that's the right word) are closed. Same for if you don't wipe it down after sanding, they can clog with dust.

Follow the guidelines, or don't be surprised if you get results different than expected.
