This is the closest catagory I could pick. I have a solid (molded together) Corian kitchen countertop and sink. A friend dropped something in the sink and cracked it, now it leaks through slowly. The crack is about 5 inches. I cannot replace the sink because it is all one solid moulded piece with the countertop. Is there anything I can use to fill in or seal the crack to stop the leaking.
Thank you soooooo much.
