Help Installing Drains in Corian Sink

[DD716TED]

We are having Corian countertops with white corian sink installed and I intend on doing the plumbing reconnection. We plan on having white drain fittings (1 sink drain / 1 gargabe dosposal sink drain). I have 2 questions that the local HD employees can't seem to answer. (1) Are special drain fittings required for use on Corian? Everything on the drain / strainer packages in the store say for cast iron sinks... (2) I am having a tough time finding white drains. I see white inserts but is this what I am looking for, especially for the dish washer / sink drain.. If I can use white inserts, I can reuse what I have... ANY HELP would be appreciated.

The white inserts are not a bad idea, because the life expectancy of white disposal flanges and basket strainer flanges is about 30 days. The inserts let you replace them easily and often.
