How do you repair a rather substantial nick in a Corian countertop?

It will have to be done professionally. Call the vendor that you bought it from. If you don't know who the vendor was, pick any Corian vendor out of the yellow pages. If they don't do repairs, they will be able to direct you to someone who does.
Depending on the extent of the damage, light sanding can be used to repair a Corian countertop. There are authorized repair technicians who can do the work, if you don't feel comfortable doing it yourself. This is a page about repairing a burn mark on a Corian counter.
