RE: spinner damage
Irrpcanada,
The other alternative would be to get an aluminum spinner but you still need to follow Ken's instructions. The aluminum won't be effected by the starter other than rubber marks that clean off with Windex. They are costly so if you don't mind the scratches stick with plastic. Aluminum can run from $23.00 to $$$$ depending on size and manufacturer. I personally like the heavy duty polished aluminum Magnum Spinners.
