Johnson paste waw will fill and hide very fine scratches, but it won't hide dents or deeper scratches. At $7 for a can it is worth giving it a shot. When it comes to removing scratches I recommend Tibet Almond Stick. It is magic! You can google it!
I would try a small sample area first in an inconspicuous place to see if I liked the results.
I don't think it could harm anything. I have used it to lubricate wood screws before driving them into hardwood.
Hi. it's interesting that you ask because I use Johnson Paste Wax on Tung oil finish guitar necks that I make. The wax also works well with shellac, linseed oil and Tru-Oil. You can use a paper shop towel to remove the wax after polishing.
Yes, you can buy or rent a floor buffing machine. You will need to get the right buffing pad for your floor. See: https://multimedia.3m.com/mws/media/834033O/3m-floor-pad-wall-chart.pdf for the various buffing pads available from 3m. Competing brands have similar offerings. For general waxing and polishing, you can use a low-speed buffing pad.
Not for used on veneers finish
It would solve your problem, but may cause many more. Why not nod just use brown paper or news paper?
