Ok, I own Novus but haven't used it yet. I assume that you would use #3 on the entire drum even though the deep scratches are only in one "panel". Correct?
The novus treatment worked great on my hollywood's. I did the whole drum with #3 then went over the worst places a cupl more times. Then used #2, thats when they really started to shine. #1 last, then lightly buff with a clean all cotton cloth and wa la, beautiful drums.
Elbow grease with #3 is the key ingredients
Good luck.
