Dash Problem

I recently purchased a glade car plugin, because my car smelled bad. It somehow leaked and ran down the dash about 4 inches. What ever was in the oil bonded with the dash and then ate through some of the plasic. Any ideas on how to fix this or at least make it look better? I guess it would be like fixing a scratch.

Thanks

Yeah write a letter to the company who makes it incl. a pic, and get them to pay for it... or duct tape.
