Man , people are truly sick these days, sorry to hear this...
Well, the short answer is no, you cannot shoot a clear lacquer( what is sold in spray cans) over urethane clear, it will literally eat it away. Paint shops can sometimes use a special "melt in" clear for spot jobs, but it takes certain prep and special blending paints and techniques to do, not a DIY thing. If you decide not to do anything, at least spray some isopropyl alcohol and water mix on it to neutralize the acids, or they could further etch the paint , even though you can't visibly see them.
Most shops would simply repaint the panel base/clear.
Good luck.
