Meguiars micro fiber correction question

[smkdya]

What speed should i set my porter cable 7424xp on when correcting the paint ? What speed should i use when polishing the paint ? I find when using speed 4 when applying 15 lb pressure the rotation may be to slow . On speed setting 5 I get much better rotation when applying 15lb pressure . Thanks for your help .

I usually use between 4.5 and 5 on the PC when using compound and cutting discs, and between 3.5 and 4.5 when using a finer polish and the polishing discs.

Just curious, would there be anything wrong with using it on speed 6? I used the 5" megs cutting microfibers the other day on my wife's Suburban and speed 6 seemed to work without too much vibration or fatigue. I've only tried it a couple of times, though, and only got the hood done so far...

Really, my PC at 3.5 won't rotate at all with hardly any pressure. I use only one speed with my pc and that's 6.

I'm not sure that 15 lbs is what is recommended for the MF pads. At any rate they have a recommended OPM rate which will be a different setting depending on what machine you have:

Are Speed Settings The Same On All Polishers

Cutting pad speed target is 4800 OPM (about 14:00 in the video) and finishing pad is 3800 OPM (about 18:10 in the vid).

5-6

The other speeds are relatively worthless for correction.

Got the XP? Mine spins fine.

And I have poor results with MF at speed 6. The pad gets matted down and too hot, too quickly.

3.5? LOL....no chance

I noticed that too. My thought was to clean the pad after each 2x2 section, and when I do, I can run at speeed 6 all day on the pc. Really, I'm not interested in cutting with a PC unless it's speed 6 with a microfiber.

One of the reasons they don't recommend running any polisher full speed is full speed with,

• Time
• Pressure
• The violent oscillating/rotating action

Tends to push adhesive technology to its limit and you'll see the pad de-laminate at some point. Same thing happens to foam pads when pushed to the limit.


I'd say most people I've talked to and worked with don't normally take into consideration the violent action a dual action polisher produces at the pad and backing plate level.

It would be one thing to turn a Porter Cable 7424XP, Meguiar's G110v2 or Griot's dual action polisher and buff out a section about 16" squarish and then turn the polisher off and call it a day.

But that's not reality and reality is guys run these polishers non-stop till a car is completely buffed out and that's a lot of punishing violent action being exerted to a thin film of adhesive holding the pad to the velcro.

Add to it the chemicals that will seep through the pad till they penetrated through the pad and hit the backing plate and add all of these things,

• Time
• Pressure
• Violent oscillating/rotating action
• Chemicals

And why is anyone surprised a buffing pad doesn't last forever?
