What cuts faster-slow or fast rotary speed?

My L5-S1 is killing me!
With dimishing abrasives, more heat/speed = breaks down quicker I assume (particles get smaller faster)



With a rotary in general, a faster speed would cut faster I assume



So...to combine these 2 assumptions, say if I was using SSR2.5, what option cuts faster?



1. 1000rpm for the 1st pass then crank up the speed

2. 1800rpm for all passes



I was doing option 2 when I needed to cut fast, now I'm thinking option 1 might be quicker???:confused: :nixweiss
 
Meh, yea, there's that...

really I'm just interested to solve what option above is faster just for my own knowledge...

I'm racking my brain on it:eek:
 
From watching the Meguiar's video I got the impression that it's better to do the first pass at higher rpm and some pressure and reduce speed and pressure with each subsequent pass.
 
wifehatescar- IMO it depends on the polish, and I'm not familiar with the SSR2.5. I'd ask PB's what they recommend.



With 1Z polishes, the diminishing abrasives thing happens just as you suspect- if you use too fast a speed you don't get *as much* cut because they break down too fast. With other products like 3M, they seem to cut better *with* a faster speed.



I dunno about any advice from Meg's phone reps. I'd ask Mike P. what *he* recommends and go with that.
 
It might be a toss-up really.

The first 30 second of SSR3 you can HEAR the abrasives on the paint!

I have an email into Steve at PB's for his opinion.
 
Faster speed will increase friction. The heat created is from the friction.



From what I've seen you don't want to heat modern paint past 120 degrees and with a rotary that is extremely easy to get to!!! I usually run at 1200 for normal polishing. 1500 to 1800 for more serious work.
