I use Storm Xtra Shine...........I put a dollop on the back of an Abralon pad (the red side) that is completely used and done.
Works for me on the spinner. I do 2 sides about 20 seconds each.
This process works for me also. I tend to do 2 sides rather 4 or 6.
Power Gel polish has, in the past, been among the less abrasive polishes. (Remember that polish is just a micro abrasive in suspension.) This is good because it allows you to make many steps along the way from an almost imitation of a 4000 grit dull look up to a gloss polish (with effort).
So, for the most part, I tried Power Gel but rarely used it myself. Among my favorites were Impending Doom's Storm Xtra Shine, Ebonite's/Powerhouse Factory Finish polish and Lane Master's polish.
The back of a used Abralon or SiaAir pad makes an excellent applicator. Once I used one, I never used any other.
Personally, I put about a quarter sized dollop on a dampened (squeezed dry) pad, spread it across the top half of the ball, BEFORE I turn the spinner on, then turn it on slow speed. Then press with medium pressure. If you start with 1500 grit or 2000 grit base, you should a shine developing after 15-20 seconds more or less. Then buff the cloud off with a microfiber towel. If you start with 500-1000 grit base, putting a shine on will take slightly more time or polish or pressure. Starting with 3000 or 4000 grit base, it will take less of each.
