The principal governing factor is that the chemical reaction occurs
more quickly at higher temperatures. That argues against garaging and
especially against heated garaging.

Other factors are second-order. If epoxying the floor allows you to
clear out the slush often, that's good; else the difference is
negligible during the winter. However, the salt absorbed into an
untreated cement floor will have a small effect when the car is garaged
wet in the summertime.

Some years ago I read that Rochester (western NY, for our distant
readers) uses 7% of all the road salt in the US. To me that's a
jaw-dropper. I wish I'd saved the newspaper article so I could
attribute it here.
