Will painted wood that has been buffed to a polished finish remain so with daily use, i.e. a desk?
With the type of prep and finish you are describing it sounds like the desk our Dad made for his masters project. It still is in use today by my little brother in his home office, the only difference is you have to know how to open the secret drawers and those can be hard to find , never made it to that level because I went into the sparky world , any time a good sanding and many coats of quality finish is used it can last generations. I love DA or dual action sanders I have found to make high end quality finishes a very fine paper is used , dad taught me to use up to 1200 wet paper for custom jobs with varathane on oak &amp; walnut that looks like glass 20 years later.
