this is my opinion on how I achieve very close results to 1500 grit polished.
grey pad on a spinner
then apply your favorite gritless polish
the grey pad is around 1500-1600 grit (P/Fepa scale <-- which is the same scale storm says the polish is based upon)
that is my preferred and easiest method but as charlest mentioned there is more then one way.
you could use 360, light 500 then step 2
or even 1000 abralon then reacta shine (but ive never tried this method)
