Don't give up:wait . using #83 with a PS will only give you half the results the product can do because of the amount of "heat" the Pc can produce, even though it states on the label for use by hand, polisher and rotary. I have found that using #83 with a rotary will work better in the long run.
Now that no one is looking :hah if I can suggest using something different after you use the #83. Do what you can to get a hold of some Poor Boy's Pro Polish that stuff is amazing.
What I have found to work for me is to apply Pro Polish with a applicator pad to a small section as if you were doing an "old school wax job" not to much though....then work the section with a polishing pad or a finishing pad...if you using a finishing pad you will need to work the section a little longer, don't be aggressive with the down pressure let the machine do the work not your arms.
Good luck
Keep us posted on how you do
