many people are doing this now days and I feel that it lightens up a room and makes it more roomy.
What you need to do is:* Clean down the entire paneled area with a solution of water and vinegar. This removes all the grime and grease.
* Putty in all holes and areas that had nails.
* Use two or three coats of a primer called: Zinzer B-I-N. very good stuff
* Apply two coats of finish coats. Will look great.
In answer to your question, I never fill in those cracks or division lines. this just gives it character.
