Never dry RC paper on the dryer unless it is on a very cool setting. It was designed to dry fiber base paper, face against the chrome for glossy, face against canvas for matte. Keep the surface polished with a soft cotton cloth and occasionally polish with a good quality paste wax then buff. Always make sure your prints are completey washed and no fixer remains, or you will contaminate the canvas, followed by contaminating every print that follows. This will allow you to have fairly flat fiber prints without much hassle.
