Be cautious where you use the 'magic' eraser. I had some scuffs on my dash that the eraser actually made worse (fortunately, I did it in a obscure location to test). Test in hidden location first. It will work in some areas, but others are more sensitive.
I think the rolls bars are more hearty and should be fine.
For the dash - ended up using Mequires Dash and Trim restorer, which worked okay.
