Working from least to most abrasive

[dotnetdave]

I have read all the advice both on here, megs US and detailing and the advice everyone give when machine polishing is to work from the least abrasive to most abrasive compound when trying to determine the level of defect removal need. Based on this i want to check i have the right order with the following products:
#80 Speed Glaze, #83 Dual Action Polish, 2 x W7006, 2 x W8006
The order of least abrasive to most abrasive
#80 & W7006
#80 & W8006
#83 & W7006
#83 & W8006

Re: Working from least to most abrasive

Dont use the 7006 pad with a DA polisher... at least not until you are much more experienced.

Depending on your paint type, something like #9/#81 could also be used with a 9006 pad, or even #80 with a 9006 pad, if you were to have micromarring trouble. But that happens in only a few cases.
#9/#81 - 8006 Very Mild
#80 - 8006 Mild
#83 - 8006 Medium

80 is less aggressive than 83

8006 pad is less aggressive than 7006 pad

8006 is polishing pad

7006 is cutting pad

i believe 7006 is not recommended for use with the G100/PC
if you are using PC then your level of aggressiveness would be
80 then 83.... with 8006 pad

Re: Working from least to most abrasive

why do you say not to use the 7006 cutting pad with a DA ? as whilst i have taken virtuall all the swirls out with #83 & 8006 i do still have some random depth scratch (RDS or RIDS). So in these areas i was going to move to using a slight more aggressive pad

Meguiar's W-7006 Cutting Pad was designed to be used only with the rotary buffer. With a DA, the W-7006 can scour the finish, leaving the individual requiring someone skilled in using a rotary polisher to restore the gloss. So while a few on various sites have used the W-7006 with the DA and got great results, their results are very much dependant on the scratch sensitivity of their paint and is not the norm as most of the time the DA/7006 combo will scour the paint. So unless you have a lot of experience in detailing and have a rotary polisher in case it does scour the paint, I would not chance it.

Hence the reason why Meguiar's does not recommend the use of the W-7006 Cutting pad with the DA polisher.

Hey Murr,

I believe you meant #9/#82 Swirl Free Polish if you have any micromarring as I am sure you know that #81 is a pure polish and contains no ingredients designed to remove marring in the paint. So while the pad's contact will in itself help to clean the paint, #81 as you know, is only to help nourish the paint and fill the microfissures in the paint.

Re: Working from least to most abrasive

why do you say not to use the 7006 cutting pad with a DA ?

It has to do with the oscillating action of the DA polisher. Take a foam cutting pad, ours or the competition, use this pad n a rotary and then on a DA polisher on a perfect black finish and the DA polisher will leave the paint looking hazy or scoured.

This is kind of hard to explain and oh so easy to show on black paint... but remember, when we're talking about basecoat/clearcoat paint systems, you're never really working on the color coat but on a clear layer of paint.

Point being if something is scouring the clear paint over a black basecoat the it's likely scouring the clear paint over a lighter color it's just that the scouring can be hard to see if you're working on a light color. Black shows everything, that's why we aways test products, pads and procedures on black paint.

A cutting pad can be used on a DA polisher successfully but when you use a cutting pad on a DA polisher you need to be aware that it's likely scouring the paint, (even though it is removing the defects), and then do the necessary follow-up steps to remove the scouring. Here at Meguiar's we historically don't teach people how work backwards, scouring paint as a part of a process is working backwards.


What color is the paint you're working on?

Is this your car or are you inquiring about this topic because you detail cars and are interested because you're always working on a variety of cars?

Hey Murr,

I believe you meant #9/#82 Swirl Free Polish.

The 7006 is perfect for putting a microfiber bonnet on and removing wax
