GREAT FIND !!
Do you know what color it WAS?
And, do you know what it was painted with?
Sometimes people will take standard latex house paint....... Which is water-based and relatively easy to peel off.
If that is the case, the paint on there is basically a cover, preserving what ever is under there. You maybe able to take a hair dryer or heat gun, and carefully soften the latex and peel it off to discover...... a beautiful Torquise, pink, yellow, or dark blue base color.
WE NEED PICTURES of the discovery !!
