Yes, two examples. The first one is like when a car owner rubs a special wax on the faded car and VIOLA; it looks like it just had a new paint job. But you know what? The car still has those dents that were previously there, but now it is sealed and protected. Much like NRS refinishing, some character from any damage may remain, but the life of the finish system is prolonged!
A second analogy is blacktopping a driveway. You’ve provided the necessary maintenance, sealed the cracks, you’ve improved it cosmetically and it is ready for service. You may still see indelible “character” marks but it now has more protection.
