Mixing M105 With Ohc...? Has Anyone Tried It???

Hi everyone, I was wondering if anyone has had any experience mixing M105 with OHC? I love the way Meguiars cuts and the way Optimum Hyper Compound lasts and wanted to know if anyones experimented mixing the two...



Thanks



ps I called Meguiars to ask them if they thought it would be a good idea and they said no. I don't know if they didn't want me to try the Optimum or just thought it was a bad idea with no bias.
 
I find if you use the right amount of 105 you can get it to cut for quite some time, although I am not sure that is how it is designed to work. Since 105 uses a different type of abrasive I don't think it would really behoove you to mix it, but you can certainly try.
 
Of course Megs is gonna tell you not to. Any company will say not to. They are not gonna say go ahead and you screw up your paint and then you bash them for saying it was ok to.

I would not try it, and not sure why you would want to really.

If Megs cuts just fine for you, why do you need the working time to last any longer if it produces the results in that shorter time?
 
I'm not at *all* opposed to mixing compatible products from different makers, I've used a lot of different mixtures that worked fine. BUT...





As noted, the nondiminishing abrasives in M105/M205 are unlikely to work optimally when combined with diminishing abrasives. Lots of reasons why and I'd certainly expect diminished cut after the diminishing stuff breaks down.



If you watch out for clumping/etc. you can extend the work time of M105 by adding water or #34. I usually add a "don't try this at home, kids!" disclaimer because there *are* potential issues, but if you want to work outside the box that's the way I'd do it. I will say that it worked fine for me, but it also sometimes *increased* the cut (and the residual micromarring) of the M105 because the water (and even #34) won't lubricate the finish the way the carrier agents/polishing oils do.



But, also as noted, when the pads are properly primed and you work the right-sized areas, M105 works pretty long. Note that it gets mixed with cut-off clear and the pad needs to be cleane out frequently for that reason alone. There's a reason why the Meg's lab guys forumulated it the way they did; they could've made it have a longer work time if they'd wanted it to behave that way.
 
I have had good luck mixing M105 with Ultimate Compound in certain cases where M105 acts up. Very high heat and sticky paint.



It does lower the cut but goes a long way to extending the work time. Dust seems to be about the same....go figure.

I'm guessing that EMIN007 doesn't really want to make it more aggressive, but rather just wants a longer work time before it starts to flash/clump/etc.



Yeah, the added cut from that water-reactivation is something I sure wouldn't want on medium/soft paint. It's not really an issue on hard clear, just enough that I could tell it was happening.

I always figure that if a given product dusts, adding something else to it won't change that much. At least that's been my experience...

I've done the same. About 70% #105 and 30% OC seems to work best. Doesn't always work though, tends to do best on softer paints. Just add a little bit of OC in until you get the results you want.
 
Just to be clear I am mixing Meguiar's Ultimate Compound with M105.



Scott is mixing Optimum Compound with M105. Correct me if I am wrong Scott.
 
Seems like everyone shot that idea down for the most part! Haha, personally I HAVE thought the same question about 105+Optimum-something. I may try it out. I don't see why it matters that you mix diminishing and non-diminishing abrasives. I understand what you are looking for..



My guess is that, yes, initially the cut would still be pretty high and then as the diminishing OHC abrasives broke down, the cut would lighten up some, but what is wrong with that? Many of the oils would still be left behind would would remedy some of the issues that one "could" complain about with 105 - drying up to much, dusting, etc.



I'm going to give it a shot, this weekend probably. Will report back.

Give M95-Speed Cut Compound a try. It has a way longer work time than M105, and cuts just as good. The finish with M95 isn't always as close to LSP ready, but if you follow it up with something like M205 you're going to get the results you're after. IMHO M95 is one of those products that got overlooked. The compound is a dream to work with, and gets the job done right the first time around. Give it a try, you won't regret it.
 
I wouldn't really start mixing stuff unless you NEED to. I have only done it on a few occasions and it was only with really weird circumstances. Like heat over 100*, way high humidity and sticky paint. For the most part the products seem to work best the way the chemists designed it to.



Also, I should note this was all with Old M105. I'm guessing the new version is much more friendly over varied conditions and may not need it ever.

Personally, If I was gonna mix an optimum product with 105 I'd choose the less aggressive polish instead of the OHC to mix with 105. That would extend work time and the smaller abrasives would probably leave a pretty nice finish.
 
To those interested, still planning to experiment with this.. just haven't had a good test subject. I did spot buff some areas with the HD Tangerine pad and 105, after priming with OHC - this may be something I experiment more with also.
 
Regardless of temps, a cool running wool pad at low rpm's works best with M105.

Usually... If not, then i switch to MV350; this compound doesn't get enough exposure

here for some reason. It's not as fast cutting as M105 but the work time is very long

and the finish it leaves is just as good.
