WOW, and I thought the Corian was the better counter over the "Solid Surface" we have in our Mountaineer. Apparantly they are made of similar material.
On our first trip with the new unit last year we scratched the counter with a ceramic salad bowl! Since then we have been extremely careful with what we put on the counter and that even includes ceramic coffee cups. ANY cup, bowl, utensil that has an unglazed bottom never reaches the counter anymore.
Good luck with the scratch removal. That is going to be one of my spring projects.
