A:AnswerDepends on what part you scratched. I did the same thing on the older version of this appliance and it was on the plastic part of display. You cant get those out. But I know you can buy a new skin to replace it and it replaces easy. If its in the metal part try using something like a rubbing compound used for a car. Make sure its not flamable or on any of the parts and I would disconnect the gas and electricity before hand but if its on the front part it might work.
A:AnswerYes they both use gas. You can use each one on different temps or the same temp. To use the full oven you can take out the divider and it will ba a regular oven.
