What can I do about the cracks in my sink?

We have some kind of a plastic material or cultured marble vanities and sinks in our house. Problem- cracks have appeared at bottom of sinks very near the drain on e sink is supposedly cracking because my husband shaves at this sink and runs very hot water. However-- I hardly ever run hot water in my sink. And I see a hairline crack forming. Any idea how to camouflage these cracks until we can afford a total redo at
least one bathrooms and later the other(master). Wondered about spit paint but never have used it and my husband never did and feels sure it would never work. so I am open to suggestions. Remarkably, o leaks Re developed. Thanks!
