Hiring a custom cabinet guy. My wife wants to paint the cabinets inside and out. The custom cabinet guy did, which to my knowledge, the usual thing and got wood with a sealer on it. He then planned to just paint the outside of the kitchen cabinets. Which is normal? Is it taboo to paint inside of kitchen cabinets? Is there a benefit to sealing instead of painting the inside of the cabinet? We need to make a decision soon, so I appreciate everyone responding quickly. Thank you very much.
