On my tub I created an accident that revealed the old color, light
blue the size of a couple of pinheads under the white coating. I had
this touch up paint in a small bottle and its half full. ..but its
hard. Does anyone know how to rejuvenate it? All I need is a dab of
this paint. I was thinking a little turpentine, but i was wondering if
that would decrease the stability of this type of paint after taking
showers?

Try to remember where you got the paint and get a replacement bottle.
Nothing else will really work. If you want to tinker, you could buy a
slew of solvents at a paint store and try them one at a time.
It might be a lacquer that could be softened with a fingernail polish
remover, for example.
When you get the replacement paint, use it, then keep the cap screwed
on tightly this time. HTH
