^ it doesn't require dismounting if you do it yourself. But make sure to cover and tape all the areas you are not trying to paint on purpose. Now, its cheapest if done by yourself. It would cost about $25 to $x.xx depending on how fancy you want it to be. I painted my own valence and fangs, costed me $6 for both satin black and satin coat - $5 for a roll of tape - and $10 for paint sheets.
