D151 vs D300 $$$

I dont think D300 has any protective properties to be considered a 1 step. I thought it was pure polishing compound. I always top off d300 with a durable sealant. And yes, it does dust decently and cut more than D151, and IMO 105

1 step = one machine polishing step that will then be topped with an LSP

All In One (AIO) = One product that has polishing (correction) properties and protection properties that does not need to be topped with an LSP.
 
Thanks everyone. I had no idea D300 was so strong. Now I really want to try it out!!!

I guess a better question would have been: Why is D151 so insanely cheap?

It's cheap because all of their pro detailer products are cheap! Or priced well for how good they perform. I can't wait to try out some d151, I think I'm going to purchase some on my next order.
 
Okayyyyy...

It seems there's much confusion and misinformation in this thread...it's all over the place. Don't believe me, start reading again from the beginning.

Below is exactly the type of comments I've seen across several forums about the amount of cut in D300 and I'd read many posts putting it just a few notches less than M105 as far as cut goes.

Thanks everyone. I had no idea D300 was so strong. Now I really want to try it out!!!

Again, In my first post I posted that D300 and M105 were comparable in cut only to find out I was wrong, per Mike Phillips's article that placed D300's cut above, or less aggressive than Ultimate Compound, nowhere near M105.

Perhaps D300 paired with a micro-fiber pad could yield results comparable to M105, but I have no solid information on this.

Regarding the underlined above, here'e Mike's article again that he update just a couple of months ago, telling you where D300 falls in the line-up of Meguiar's products. I think he would know what he's talking about, and I'll take another look myself, but I don't think I mis-read it.

Here's the article again... (and Vegas pointed this out even before I did in this thread.)

Note what Mike said at the bottom in red.

SwirlX is discontinued or is going to be discontinued and a number of new products have been added that use SMAT

The D300 will fit in-between the Ultimate Compound and the Solo M86 and the D301 would be either in front of M205 or behind it



Note where Mike stated D300 would fall where cut is concerned...where Scratch X would be.

This means D300 has more cut than D151, but less than M105.
It also means D301 has less cut than D151 and according to Mike, maybe even less cut than M205. Left side of photo = lots of cut progressively lessing in cut as you move right.


Hopefully Mike will chime in on this.

I'm not sure how D300 and M105 compare from a cost standpoint, but a quick search would tell you.

D300 on a MF cutting pad will cut almost as well as M105 on foam and finish better on most paint.

It's just that using those mf pads are such a pain in the ass!!

Good catch, sorry i was half asleep writing that. :buffing:

Wow! My experience with D300 is drastically different than Mike Phillips. From what i've experienced On MF pads D300 cuts awesomely. On a heavy cut foam I think it cuts equal or slightly less than M105 but more than UC. It is also MUCH easier to wipe clean than M105, virtually one wipe done! There is plenty of dust with D300 though. I find sometimes 105 is hard to wipe off.

Just to be clear from my previous post, I did say the above. As stated I have no experience with D300 and micro-fiber pads. I have them both, but haven't used them.

I based that comment on what I've read about the combination of the two products together. I have a hunch that M105 used with the same micro fiber pad you'd likely see an even greater increase. That's just a guess based on Mike's knowledge of product aggressiveness.
 
My go to compound has been D300 on a MF megs pad, it cuts great and finishes down good.

This past weekend I was working on a Nissan Altima that was real rough with rids all over the car. While switching backing plates I forgot the spacer and long story short messed up the backing plate for the MF pads and had to use Megs yellow foam with D300. I did not get to try the MF/D300 on this car but have used the combo numerous times. The D300/yellow was not cutting as good as I like and was taking real heavy pressure, speed 5-6 and 2-3 section passes to get correction and was still leaving more than I like behind.

I borrowed some M105 from a friend and tried the D300/M105 combo I hear about online. Primed the pad with the D300 then 2 small dots of M105 2 of D300. The cut was better letting me ease up on pressure some and got me down to one or two section passes to get better correction.

It dust a lot more than D300 on MF pads and did not finish down as well. The combo worked and I will keep some M105 around but I like the D300/MF combo better.
 
So... from what I am understanding:

1. D300 (on it's own merits) has slightly less cut than M105.
2. D300, when paired with MF cutting pads, has equivalent if not more cut than M105 paired with traditional foam pads. *paint dependent
3. D300 & MF pads typically finishes out nicer than M105 & foam pads. *paint dependent

This makes sense. Especially when considering how SMAT compound and MF pad technology work..

Also, someone was mentioning the high amount of fillers in D151. That may be the case. I have always wondered why it was so freakishly thick in consistency. I must, however, say that it has a very decent amount of correction ability and for light-moderate swirls it can take care of them with ease and pass an IPA wipe down.

Thanks everyone for the in-depth discussion and thorough answers about these products!
 
I find the D300/MF still has less cut than 105 foam but longer working time, less dust and easier wipe down.

Everything thing I read on D151 it thick to help stop slinging.

I finally picked up some D300 and have been playing around with it on a recent correction job. I am AMAZED at how well this product finishes down!!! This will be my new go to compound. I love the longer working time over M105. I love the low dusting. I basically love everything about it.

Here is an after shot (sorry, no before) after wet sanding with 2000 grit by hand, D300/LC CCS Yellow/849X, D300/LC CCS White/PCXP. I was truly amazed at how haze free the finish looked for such a strong compound.

Really? I love them. They last forever and you only need a couple per car.

It's the constant cleaning of them; it slows you down. I prefer yellow B/S with it.
