Most of the stuff people put on floors to hide minor scuffs, scuffs worse that the floor finish and doesn't wear or resist soiling as well. If you put any crap like Rejuvenate on the floor, make sure there's a way to remove it when it goes bad. The only one I've seen that got a good review is Bona Refresher. Before applying any coating the floor should be immaculate.

I didn’t come across Bona

Refresher in any of my research

so surely will check into it.

I did find a lot of comments about bad results from various products so really appreciate your time and info.

A "wipe on" product is going to be temporary. Why? Because it is a polish. Like the old fashioned wax polishes grandma used to use on her linoleum, today's "wood polishes" (Like Restore) are a 6 months "fix". And then they look worse than before the application. So what to do? Add more of course! And then 6 months later, the floors look EVEN WORSE! Grrrrr! What to do? What to do?

The best thing to do right now is either A) do a buff and coat (like the painter suggested) and give yourself another 10 years with a great looking floor or do nothing and live with it for another 7 - 10 years.

I'm worried the dull areas are the beginnings of "wear through". If I'm right, a buff and coat is the BEST option. Anything other than that, could complicate things in the long run (7-10 years from now when the floors MUST be refinished).

Some photos of the "dull" areas would be appreciated. These are the areas that are the problem areas and could be the indication that the floors need a full sand/refinish sooner rather than later.
