Difference between Megs #3 and #80

Is the only difference between the two the amount of cut? It looks like #80 is more abrasive. I dont see much discussion on here about the #3 machine glaze and I purchased the #3 after ordering my PC and before reading all of the posts about speed glaze. I wanted to use the #3 after DACP but it seems like I would be better off with the speed glaze instead. Also, is the machine glaze meant to be applied by rotary only? Your thoughts please.
 
Machine glaze if I remember the label correctly has a cut of like 1 where as #80 has a cut of 4 on the megs chart. You might need something with a cut to it after DACP just for the fact that hazing may occur and the #3 will probably cover it up if nothing more. You can in fact use the PC to apply #3, it works very well.



I would suggest if you had to choose between the two to pick up speed glaze.
 
Yeah, #3 (and #5, #7, and #81) is a "pure polish" in Meguiar's-speak; they're *functionally* nonabrasive on automotive paint. #80 has a bit of cut and breaks down into something very much like the aforementioned products.



Use #80 after the #83, it's a time tested combo. You could then try the #3 over the #80 and see if you get a little more depth and/or gloss.



You can apply #80 and #3 by hand or PC, or even by rotary, but almost everybody just uses these products by hand or PC.
 
80 to 81 should look good. The 81 will add more depth and wetness. I tend to use VM or RMG now though.



81 is more user friendly than the 7 to remove, both produce apperances alike. I believe the 81 is formulated more towards modern clearcoats.
 
Both #3 and #81 are more user-friendly than #7.



The difference is that #81 is good for hand application and #3 is optimized for machine application - hence the name.
 
Yeah, there are only minor differences between the Meg's "pure polishes". Even the step #2 of the Deep Crystal system is basically the same stuff. The most user-friendly of them all (IMO) is the #5 New Car Glaze. All but #7 are pretty easy to use and I only use #7 on single stage (and only *very* rarely at that).
