D/A Polisher Cutting Summary

[sobhark]

Hello,
I just got a D/A and I was reading lots and lots within this forum and some others.

Here are my summary :

Pads :
- Cutting pads don't work so well on D/A, and NOT recommended by Meguiar's.
- Clean the pads with terry cloth when wet, and use toothbrush when dried.

Machine Speed Setting :
- Faster = more cut
- Slower = less cut
4 - 5 When cutting
3 - 5 When polishing
2 - 3 When applying wax

Pressure :
- More pressure = more cut
- Less pressure = less cut (pretty common sense huh?)
*BUT* Applying too much pressure onto the machine will cause the machine to only vibrates and NOT ROTATING (spinning). Since the pad vibrates so fast, it's hard to notice the rotation of the pad. So make a mark
on the edge of the pad, maybe with a marker pen, so you can notice weather the pad is spinning.
- If the pad doesn't rotate, then it is almost not cutting the paint, since it only vibrates. Comparing to the rotating motion which can provides lots more cut.

Product :
(This is from what I have in my arsenal)
- M105 - For deep and seriously scratched paint
- UC - Restores clarity of the paints, also remove scratches
- M205 - Normal polishing, removes light swirls

Finally, let's discuss about and bring the confusion to the end!
Or probably just mine.

I believe each variable, speed, pressure, pads, and products.
Let's discuss on how much weight does each variables has.

Assume this is a equation for "Cutting Power"

CUTTING POWER = ( A x Pad types ) + ( B x Pressure and Speed ) + ( C x Product Type )

I hope whoever reading this will get my point >__<"

So the weight, A B and C, which one is the greatest?
For instance

If
Case A : UC with polishing pad
Case B : M105 with finishing pad
Assumed the type of finish is the same,
both cases are applied with the same speed and pressure

Which one has more cut, A or B?

I hope whoever reading this will get my point >__<"
And let this thread be an informative one for others who is getting D/A
like me.

DISCUSS!! ^^

Re: D/A Polisher Cutting Summary

You are definitely on the right track - read through Let's Talk About Total Cut for more info.

As to your specific example:

If
Case A : UC with polishing pad
Case B : M105 with finishing pad
Assumed the type of finish is the same,
both cases are applied with the same speed and pressure

Which one has more cut, A or B?

There is a bit of a flaw in the mix you suggest. With M105 being a very strong compound we would never suggest coupling it with a finishing pad. While total cut is indeed based on the combination of all variables, there are some things you just would never do - like apply a pure polish with a wool pad at 900 rpm on a rotary buffer, or apply our most aggressive compound on a finishing pad for defect removal.

The idea behind the concept is to show that you can vary the cut of any liquid depending on how you use it. We've actually cases where someone found ScratchX 2.0 applied by hand wasn't quite getting rid of all their defects, so they asked if they should then step up to M105 on a cutting pad with a rotary buffer. Well, there are probably a few dozen smaller steps in between those two extremes!! Our recommendation in such a case would be to either step up to Ultimate Compound applied by hand (assuming the user lacks even a D/A buffer) or to stay with the ScratchX 2.0 but use it with a D/A buffer on a polishing pad. Use the same liquid but step up the aggressiveness via application method (and that can be a rather sizable step up) before just grabbing the most potent combination you can find.
