What speed should I be running on the steps with the meguiars mf kit?

And what speed to apply Black fire wet diamond?
 
I run the cutting pads at speed 5 on a PC and speed 3-4 on the finishing pad. Speed 2-3 will be fine for the BFWD on a finishing foam pad.
 
Ok! Any other input and tips are appreciated
 
If you have the older model 7424 and not the XP version you're gonna have a hard time using this system. The cut portion needs pressure and the 7424 has a tendency to stop rotating under pressure
 
For the cutting process you want to make sure the pad is rotating, so adjust your speed accordingly. You don't want to run the tool at the highest speed if you don't have to as the excess speed will generate excess heat and you could experience de-lamination of the microfiber pad.

Also, see this thread for a tip to help you see your backing plate rotating...

Also for applying any wax or paint sealant with the soft foam pad, you don't need pad rotation but you'll find the pad will glide over the surface easier at the 3-4 speed. Lower speeds will work but if you pay attention you'll notice it seems like the pad is lagging behind as you move the polisher. Not a big deal just a tweak of technique.

I used to recommend using the 3 setting all the time for machine applying waxes but now tell everyone the 4 setting. Think I even did this in this live broadcast when we machine waxed the 1965 Valiant.

I just finished my car using the microfiber system with a pc. I used 5 for the 300 cutting and 4 for the 301 polish part. I did have 2 different pads that I swapped out after every 2 ft area and then just used the brush method to clean the pads. I think going higher than 5 would have speeded up the process but didn't want to burn up the pads and have to wait to get new ones. I had one 3" pad fall apart but it was just me being lazy. I laid down the nylon brush I was using to clean the pads and couldn't find it. So I grabbed a little copper wire brush and thought I was almost done, the first pad cleaned up well but the second I must have pressed the brush too hard it caught the fibers and ripped the microfiber part right off. Stick to nylon or compressed air and you will do fine. I did both and found the brush to be better and faster than the air compressor.

Correct.

We see a lot of pad failures and the cause is heat, which is created by pressure at high speed over time.

That's why Meguiar's doesn't recommend using their microfiber pads on the 6 setting of the G110v2 and that would hold true for the Porter Cable and the Griot's Garage polisher.

If you use the highest speed setting to work faster and thus get the job done faster you will effectively have pushed technology past its limit. By this I mean you will have pushed the adhesives that hold the pads together past what they are able to withstand.

It's all covered in this video we made here,
