Hello,
My question is in regards to #9, #80, and #83 from the Meg's Mirror Glaze line. What would be some good examples of when to use each?

Also, what order would they be in according to their cleaning power?

Thanks in advance,

83>80>9....83 would be prolly a 5-6 (dont quote me i have never used it) and i know that 80 is a 4, #9 is a 3 on Meguiar's 10 point scale.....

I hear 83 is finicky on a PC, so i would suggest rotary use but never done it
I feel that 80 is a mild polish with not much cut, it does leave a brilliant shine though..and 9 in my honest opinion is dang near worthless at removing defects...it merely contains a ton of fillers that will mask them...but some people are fine wit that..not me i would rather remove as many as i can and then go to LSP...they will eventually come back if you dont then you have to polish again and so on......

 

This is a question that needs to be explained properly for you to fully understand it.

This can be a very technical question and answer...so , RockPick, Boss and Gip should be your go to people for this question.

FWIW, Cuts are be used as a guideline on some products but this can vary based on a number of factors. (a lot of factors)

Personally I only use Cut Scales for Megs and Menzerna products, b/c they list it and it tells me how much polish (not cleaner) I am using.

Other products don't really have a "cut" number b/c they can be treated so differently based on those "other" factors that come in to play.

Such as:
Type of DA, Rotary, RPM's etc
Pressure
Work time
Product make up
Pad choice/speed

This is one of those times when you need to really know the product lines to fully understand their behavior, when to use them etc. Like I said, RockPick, Gip and Boss is who i would listen to regarding this question, no offense to anyone else.

 

x2!

 

I agree with RR, there are a lot of factors that are going to influence how much cut a product has.....some of which he mentioned...my response is as follows...

If you are wanting to know the cut of the polishes themselves in meg's line...they are listed above in my previous post...the factors are a completely separate issue and i take it that you are wanting to know the aggressiveness of each product giving the fact that they are all used in the same context

Take this scenario....83 on grey LC pad at speed 5 vs. 80 on an orange pad at speed 5...weird example i know...but the result would be 80 having more cut in this situation than 83 because of the pad choice..which we know by themselves would not be the case....get my drift here OP?

YOU will have to determine the other factors (pressure, speed, pad) and go from there but like RR mentioned it is always best to know 1 or 2 lines so that you can play around with the factors and find the best solution.

 

Lake makes a Grey pad? Or is your White pad so dirty its grey?

Not trying to start an "who knows best here" but the OP is has somewhat of a hard question to answer...the answer can be very overwhelming to a newcomer and just going by cut on the bottle is not the smartest thing to do.

Combining the right cut with the OP's question of when to use which one is much more difficult to answer given we don't know the condition etc.

Yes it can be very simple for those who understand cut numbers and other product nomenclature naming conventions, however, to me, this is right in the wheel house for RockPick given his background with Megs products. I also know that my post is a tad long winded by now and may not necessarily be needed. Just throwing a tad be of caution when answering questions from the newcomers. Make sense?

Or....screw me, maybe I am just over OCD'ing the question.

 

#83 is more aggressive than #80 and #9 is less aggressive than #80.

That said, let's discuss each...

#83 is the highest cut product that is recommended by Meguiar's for use on the PC. Good times to use this product would be with VERY heavy swirling, micromarring, oxidation, or other 'heavier' paint problems. Polishing pad only.

#80, like #81, is a very good 'all round' type of polish that can be used for the heavier problems (will require multiple passes) or a good choice for lighter swirls and minor problems. In short, it's a bit more 'multi-purpose'. #80 is an oiler product than #81 and thus, you can 'work' it longer on the PC - which I like. I buy #80 by the gallon and consider it my main 'go to' product with a Meg's yellow polishing pad.

#9 really isn't as aggressive as Meguiar's states, in my opinion. In fact, it's not abrasively aggressive for the most part. #9 is part of a more peculiar group of polishes that combines the use of a light abrasive with the filling power of very very very fine kaolin clay. Because it's so fine grained, the 'filling action' of the product far outweighs the cleaning (abrasive) action. Really, in my opinion, the light amount of cut that #9 carries is more of a good cleaner to remove the crud that may be in and down in the swirl/scratch versus actually abrading the area around the swirl mark or scratch to make it level. Again, it relies on the fillers in it to 'fill' the swirl more so than to remove it. Should be used with either the polishing or, sometimes, the finishing pad.

That said, it's not necessarily a bad thing. As a last step, immediately before going to your last step product (or pure polish), it can add a nice pop and conceal any very light paint problem that is still there prior to the LSP. I use #9 on both my, as well as my client's, vehicles on a fairly frequent basis to deal with that last little bit of mar that I may have accidentally induced with a 'drier than it should have been' pad.

Another thing to consider with these products is color. If you're working on a dark color, #83 is pretty finicky and you'll almost always have to follow with a lighter action polish like #80 to remove the light marring that it will induce. This marring is induced because, in my opinion, the PC just really isn't cut out to deal with #83 too well. I use #83 with the PC but, I still gripe - even after using it for several years now.

Of that array, #83 is the least used product... followed by #9... followed by #80. I use the heck out of #80

That help a tad?

That is why I suggested you hold off and wait for RockPick to see this thread.

 

We need that Meguiars product chart, post it up RP !!

 

Here it is... even though it's not pertinent to the OP's original question.

 

I figured if the OP was asking when to use what product and what the cut scale was than it might be a good idea for him to have the chart.

Cut me some slack !!

 

[QUOTE=RollingRock]Lake makes a Grey pad? Or is your White pad so dirty its grey?


I get exactly what you are saying...it prolly wasnt something to get into with someone with little experience on that particular line...and yes...black not grey

Well, I was going to add my 2 cents... but I think RP about covered it.

 

I would like to thank everyone that gave their part in this thread. Like always, your knowledge is priceless and a great help. I plan on utilizing these products on my pc with megs pads. The chart is a great help, the first time I saw someone post it I printed off a few copies and have it readily available for reference. I will pretty much be using these just as the chart shows.

Thanks again RockPick for your post, it really cleared up what I was wondering about all 3 products.
