My 15 years old Enamel Kitchen Sink has a scratch caused by the sink

Is there any kind of paint I can use to paint the white enamel sink

The sink protector damaged the sink...

Home Depot will have the little bottles of touch-up paint for porcelain
sinks/tubs. I doubt that will stand up to your sink "protector" any
better. May be time for a new one.
