Menzerna FG400 or Meguiars 105?

[Tector]

Anyone have a preference for one or the other? I am using a Flex 3401.

Obviously this depends on the conditions and what you're hoping to achieve. I personally prefer FG400 because I feel like it has a longer working time and a stronger finish. I also feel like m105 dusts a lot.

Either way, I have both and have used both. They both produce nice results. I suppose you could "finish" with FG400, but you really do want to follow with SF4000 or SF4500. I don't think I would want to finish with m105.

My opinion, of course. (GG, Rupes 15)

:iagree:I have the Flex 3401 VRG and not to put down MEG 105/205; IMO Menzerna FG400/SF4500 (or SF4000 I use the former) are just better. The FG400 corrects faster and not as much dust (all have dust). I would do a side by side comparo (I did) and see what you would prefer. I gave away my Megs to an AGO person because now I only use Menzerna.

Your conclusion could be ENTIRELY different than mine...this is just my $.02 cents worth.

I have both, but I have a lot more FG400 in stock, if that tells you anything. The one bottle of M105 that I have still has a lot of product in it. I have to keep replacing the FG400.

Agreed that M105 dusts a lot more. Here's a very in-depth comparison that's pretty awesome:

Ultimate Compound Showdown: Meguiar's M105 vs. Menzerna FG400 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums - Camaro5.com (http://www.camaro5.com/forums/showthread.php?t=264488)

I have both, and couldn't tell you which one I reach for more often. It just depends on too many factors... (level of correction wanted, type of paint working on, what pad I want to use, etc.)

I switched from m105 to fg400. I like fg400 with my 3401. But you should also look at m100. I plan on trying that next.

Interesting from the Helme testing that both performed better with heavy pressure at speed 6 and then reduced speed to 4 during last two passes with same firm pressure.

I know some on the forum.have been using the 4 firm passes followed by 2 lighter passes technique.

I think you mean M101, not M100. M100 is for wool on rotary applications (not that you couldn't get results with other systems). M101 is for any pad on any machine.

But I completely agree that FG400 vs M105 isn't the best comparison with more recently available offerings in the US from Megs.

M100 really shines when paired with the Megs DAMF system.

Cuts really well.

Hybrid pads and Menzerna polishes are where it's at on the 3401. Just sayin...

There's a reason for that :dblthumb2:

I never found M105 it to be a great product. IMO, FG400 is more versatile, I would use FG400, Scholl S0, M100, or M101 over m105 anyday.

[hernandez.art13]

I am getting a gallon of M100, liked it just as good as FG400 and way cheaper than FG400 and M105.

Did a side by side comparison over at Meguiar's TNOG, FG400 vs M100. Both came pretty darn close FG400 did finish out better, but after polishing both looked great. So it didn't matter really, was removing 3000 grit sanding marks.

Was doing my D151 experiment. (Kyle was there)

You can keep working M100 since it is SMAT, however, FG400 does finish looking great, but if you need more than you'll have to apply more product since it is DAT, with M100 just a spritz of water and you'll be back in the game. (for the most part)

Also, since most of the time we will be polishing after FG400 or M100, then IMO both finish out nice enough where the polishing will do the rest of the work. However, some people do use FG400 with a polishing pad, so there is that also, but that is a different point that I am trying to make.

Plus M100 is known not to dust. (I've used it numerous times over at Meguiar's Headquarters)

If my knowledge serves me right, the compounding step is to remove paint defects, and the polish is just to refine hazing from the compounding step.

So sure FG400 does this in 1 step, cut and polish, but most of the time we are going to polish anyway.

So M100 might leave some hazing from the compounding step, but a polish such as M205 fixes that right up and if you need just a bit more working time, then just add a spritz of water.

I don't believe you can do that with FG400?

Also, this is just my opinion so could be wrong. If any of you all want a straight forward answer then call customer service, but then you'll get the "The product was not designed to be used that way" answer lol

That's why Meguiar's TNOG is awesome, it's a no holds bar when it comes to detailing. :props:

Just trying to help :dblthumb2:

I find M105 does what it's supposed to very well but it's more difficult to work with. It seems to start to dry out quickly so I always give it a spritz of something part way through the cycle. It dusts quite a lot as well. On the other hand it cuts very well and finishes down very nicely because of the SMAT abrasives. Another thing to keep in mind is that you can simply stop in the middle of a cycle for that reason. Can be handy when you don't need as much cut.

FG400 is nicer to work with but must be buffed through a full cycle. It finishes down very well because the DAT abrasives as long as you fully break it down. I am able to get LSP ready results on my hard Audi paint with this and a Cyan Hydrotech.

I have both and prefer the FG simply for ease of use and less dust.

Actually this is a moot conversation. Technological advances in wet sanding will soon render harsh abrasives and pads obsolete. I am a firm believer in the 3M 3000-5000 Trizact system. Soon 6000 grit papers will be available.
