So I built this mahoganny deck, and the Misses decides on Italian-style,
wrought-iron chairs and table, like she's sipping vino rose in the piazza.

Now I'm pondering how best to protect the deck's wood surface from movements
of those metal deck chairs?

Rubber feet? Cork on the feet?

Is there a product which will glue on / wrap around chair legs that works
well?

Thanks in advance,

Guido
