don't need to sand down to wood. With many woods, whatever is already on
the surface is better to paint over than bare wood, anyway.


In a question involving a different but similar project, *priming* over a clean, lightly sanded surface that still has paint is no problem, correct?


Not that I know of. Priming over a surface that has different,
contracting colors can help keep the top color even.


Smooth is relative with paint, as well. I can't tell you how many times
I've sanded a drywall patch "perfectly smooth" only to see the borders
after painting. If there's any texture or artwork on top, it often hides
those imperfections. But a single color, smooth topcoat will often show
them.



The solution might be building up a couple layers of primer with flat
sanding in between coats. Good auto-body guys are maters of this.


I don't want to lose the original artwork completely, since it will be my guide when re-painting.

But as far as sanding *after* I finish re-painting. Camn this be done without having to worry about bleed over?


I don't know what "bleed over" means, and I'm certainly no paint expert.
But I would never sand the final, finish coat of paint. Maybe some do.
