Issue with Corian counter top
I recently had my kitchen refinished and I had a Dupont Corian countertops installed along with a new corian sink. The installer finished in one day and as I looked at the finished product, I noticed there were two large areas (about 1 1/2 feet wide) where it was very visible that the area of the countertop had been buffed. I was very upset when I saw this and I questioned the installer, who informed me that it was totally common with all Corian countertops. The area where the dull, buffed spot, was (as he said), the area where the countertop seams were. The installer said that the buffed area would fix itself over a period of 3 weeks. He said that the area fixes itself as you (I) continue to clean it with warm water and soap.
I am concerned that the istaller was full of $hit. Please help.
