W Wolfer:
You've misread the link. It is traditional sealers in a can that must be reapplied, not Stoneguard:
"Stone manufacturers recommend applying a chemical sealant every 6-12 months. However, the protective capabilities of these chemical sealers are minimal for acids, alkaline, and food bi-products. StoneGuard® will eliminate your need for these chemical sealants."
I had to pay tuition and travel from Florida to Chicago for training to become an authorized Stoneguard applicator, so it's not a DIY project. I'm driving to the other coast of Florida tonight to do a Stoneguard job tomorrow.
Stoneguard comes in gloss and matte. It is easily removed if you want to go back to the natural finish and subsequent etching.
