A very durable finish is an oven-cured catalyzed conversion varnish top coat. It provides a clear, non-yellowing, chemically-resistant finish. The finish is smooth and has a pleasing sheen.
The least durable top coats are lacquer and catalyzed lacquer. Just a few years after lacquer-finished cabinets are installed, the area around the pulls and knobs develop a tacky, dark color. That is the lacquer wearing down from everyday handling and exposure to water (sink), detergents, chemicals, and steam (coffeemaker and dishwasher). Lacquers also yellow over time. This does not happen with a catalyzed conversion varnish.
