M85 vs M105

I'd like to know too. I've only used 105...by hand and with the PC. Heard that Meg's has even revised the forular for DA use. Additionally, have come out with M205 for a follow up/finshing polish to 105.
 
I would spend a bit of time over at meguiarsonline for more detailed info, but suffice to say that M105 compared to M85 is like comparing a horse and carriage to a ZR1.



M85 was the strongest compound that Meguiars offered for years--suitable only for rotary application(recommended for wool pads) and based upon their diminishing abrasive technology. A fine product, but not the technologically advanced M105.



M105 is based upon new "micro-abrasive" technology that allows the product to cut more and finish better--a detailers dream IMO. There is more of a learning curve with M105, but well worth the effort IMO.



Having used *gallons* of M85 over the years, I haven't touched it since M105 hit the scene. Use both if you wish, but don't let the price of M105 deter you--products are cheap if you are charging accordingly.
 
M105 uses non-diminishing abrasives which is a much newer technology. It cuts fast but will work as long as you work it and creates a very beautiful finish that reduces the need to polish out swirl marks induced during compounding.



M85 is a much older technology and tends to scour paint. It takes more time to remove these marks.
 
Was 105 really revised? From what I was reading they are exactly the same product... but the new labels says it is specially formulated for DA and rotary use were as the old one only says rotary.

It was reformulated for DA use and Meguiar's announced it at SEMA.

i guess we all have to find out the hard way... test comparison

why does it matter to you?



products are revised all the time





as long as it works .....
 
Holden, have you even tried M85?



First of all, M85 is a serious compound to be used with a wool pad for the removal of wet sanding marks. So yes, the finish will have some mild holograms (easily removed). But then again, what heavy compound combined with a wool pad doesn't leave holograms?





M105 can be used with any pad on the rotary. Also, you can vary the cut by using different amounts of pressure.





When using the a D/A and the older M105, the product would tend to gum up on the pad. The new version corrects this problem. Unfortunately, I cannot give out any specifics.
 
i havn't used m105 always wanted to try it out, but i've only seen it online. But as for the m85 i've used it with a wool and the w8000 for lighter swirls and it works wonders. I can't give any insights on m105 but m85 seems to do the job for all of the clients cars so far.

That's interesting. It used to be that M83 DACP was the strongest of Meguiar's compounds that they recommended you use with a DA/PC.



My... have times changed.

does anyone know if SIP dose anything like M85 or M105? I notice alot of people use this product and was thinking to try it out too.



is it like a compound?

SIP is a "middle" polish. It's quite popular, works well, finishes well, and has moderate cut. However, M105 will offer a significant amount of cut over SIP while finishing relatively similarly depending on the application. Keep in mind though, you don't always want more cut.



For severe corrections M105 is the way to go IMO, but for a mild to moderate correction SIP is a great product. If you want to save a considerable amount of money I have found Meguiar's M86 to perform very similarly (feels similar, working time is similar, etc) to SIP at a fraction of the cost.



M86 also seems to work extremely well on single stage paint (My guess is that it has chemicals for "fresh" paints that also happen to work well on single stage paints).
