Rotary speed?

[imported_Dave KG]

For general defect removal stages using medium polishes and light compounds I will use the ortary at around 1500rpm to work the products (generally Menzerna or Meguiars for me). This I find a perfectly effective speed and maing several passes (sometimes ten or more) gets the job done, then I finish off at about 900rpm with a couple of pases to refine the finish and remove any light hologramming that may have been inflicted...



For more aggressive compounding, I still generally stick to 1500rpm, but have been known to go above 2000rpm for more severe work - I used Power Gloss on a W7006 pad and 2000rpm+ to knock back orange peel effectively, and used slower speed on final passes to refine the finish... Then a finishing polish to remove the light hologramming using the rotary at high speed invariably left.



For finishing polishes, I rarely venture above 1200rpm - no need to.

I like 1500rpms moving the machine fairly slowly - I go to maybe 2000rpm max for cars, but I've used 2500+ before on aircraft paint and metal surfaces.



1500 might feel slow at first, you can judge if you're running it fast enough by the heat it leaves behind. If your panels are cold after polishing, try slowing down the machine or bumping the RPMs a little bit. They should be warm, but not uncomfortable, to the touch.

I have a PC 7428 Rotary and I never ever go above 2000 I always stay at around 1500, which unfortunately there is no setting so I try to just put it inbetween 1 and 2. What amazes me is the 7428 goes up to 6...what the heck am I going to do at 6 other then maybe cut down a tree.

There is a post over at MOL about the speeds to setting relationship for PC 7428.
