Skip the 1500 Siaair pad and go straight to Storm Step 2. The Step 2 will bring it to a 1500 grit finish similar to the factory.
If you want the "near" factory finish, start with a 360 grit pad on 4 sides for maybe 30 seconds a side, then 500 grit for 10 secs a side, then Storm Step 2. No further polish after the Step 2. You should be able to see some of the sanding lines from the 360 grit pad.
I suspect when you used the 1500 Siaair pad, then the Storm Step 2 you removed everything from the 500 grit pad. The ball needs those deep peaks and valleys from the lower grit to handle the oil.
Hope this helps.
