Just a quick update so you don't all think, that having asked, that I'm now ignoring your sage advice. On Monday, I had time to stop in the supermarket to look at floor waxes. Wow! Are they expensive at $6.99-$8.00. It's unlikely I would use floor wax for anything but these experiments, so I thought I'd price the various auto waxes/scratch pens that have been mentioned. If they are comparable in price, I suspect I'll be able to use it on my 1:1 vehicle and thus be a better value price and utility-wise.
Unfortunately, I had to work late last night and the auto parts store was closed when I got there. I will try again tonight or else check out the "medium box" store nearby where I might find both the floor wax and automotive products at lower prices.
In the meantime, I found a safe (and tasty) way to cover the scratches:
