There, it feels very slightly "tacky" and if I touch it with
my fingernail, the paint is extremely soft, and peels off in
small areas. The material that peels off is "rubbery" in
texture.


Oils and salts from your skin is reacting to the paint. Try a some
denatured alcohol on a small spot and wait a day or so to see if that
clears up the tackiness.

Or leave ir all alone and cover that area with a thin backed cloth
covered material with or without padding..

And try not to lean on the paint.
