Hey Jody,
I changed the cover on my Animal several times (from polished to shiny) and it responded fine to whatever surface I put it at. For oil though, I had to keep it at 400-600 grit, had to help it some due to the spin time. Shined up, it played well on the med/lite conditions for me. Hope this helps some...
