Difference between Megs #3 and #80

[imported_BigTinVA]

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.

what about #80 then #81 ?

how does 81 compare to 3?

ive read that 81 is like a user friendly 7

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).
