Yep, a crisp cut off a track saw is step one.
Sanding the edges up to some fine grits without rounding them is step two.
When i used to prep mrmdf for the spray shop we used to get the edges to look almost polished, and even then the paint would show up a saw mark every now and then.
I didn't have the patience for it.
