I might add that if you do plan to spray on a light satin finish coat, you would be best to prepare the surface by wiping down the existing finish with a good denatured alcohol
Let me tell you something about denatured alcohol, it has oil in it. I work with fiber optics for a living and denatured alcohol is a huge no no because of the oil in it, you want 99.9 % alcohol.
You can special order it at your local pharmacy or get it at places that cater to fiber optic splicers.
I see this comment all the time and just shake my head and roll my eyes.
Edit: just use plan ole alcohol 70, 80 90% doesn't matter you just don't want to use denatured.
