If you have a good quality finish system from the manufacturer, adding gunk on top of it will actually damage the finish, not protect it. A plain bit of soap and water cleanup is all that is needed.

Thank you. I had never heard any mention of applying a coating, but I just thought I'd check to see what others are doing. Thanks again.

Most kitchen cabinets are finished with a post-catelyzed conversion varnish. All that is ever recommended is lukewarm water and a dash of soap.
The only problem I could see if the cabinets are put in place before the cabinets cured.
