meguiars ultimate compound

**choijw2** · 08-31-2015, 09:26 AM

So i tried meguiars ultimate compound for the first time yesterday on a BLACK bmw x3. (just small spot to test)

tools wise, i used GG 3" DA with hydrotech blue foam pad with speed set at 5
I know this isn't really good set up, but it did remove good amount of swirls but paint came out little bit milky, which i did not expected at all.

my understanding is that this product is one step polishing, so I should be able to seal/ wax right after this compound...

i also tried less aggressive pad so i dont think pad choice was the issue.

what did i do wrong? maybe i didn't polish long enough?

I use UC on my 335, and have no issues with milky paint or hazing. You can use it as one step, though I always follow up with Ultimate Polish to ensure all the fine scratches are removed.

On another car I did find some hazing or build up of UC, but found that it was due to using too much and it drying out on the pad. I have since made sure that I prime my pads with a small spritz of detailing spray, use only a tiny amount of UC or UP after loading the pad, and occasionally spritzing with detailing spray when the pad feels somewhat dry. Also, don't forget to clean the pad on the go.

thank you for your respond roguerobot.

maybe I did use too much and thats what caused the haze.
I tested on maybe 6 sq inch area and used 3 small dots on 3" pad.

I did prime the pad before use,
i spread the compound all over the pad with my finger and gave one quick spray before use.

Meguiar's Ultimate Compound often can be the one
and only step needed before LSP applications.
Let me emphasize that: Often can...not always can!!

Note:
I agree with your evaluatin on your "set-up":
Could be the root cause of the milky looking result.

Regardless...In this particular case:
An additional polishing step using a less aggressive
product...such as Meguiar's M205...may be just what
is needed to clear up the milky haze.

An even less aggressive polish, like Meguiar's
Ultimate Polish, might also do the trick.

Not exactly a one-step product. The normal process for buffing on scratch-sensitive clearcoat paints is,

Compound
Polish
Wax

It's possible to get away ONLY with the Meguiar's UC but this depends on two factors.

1. The color of the car - Black is usually not a color you can get away with only using a compound.

2. Your expectations for the words.... good looking finish - Again, black is not the best color for a one-step process using a compound.

My experience is when buffing with small pads there's an increased risk for leaving marring versus larger pads. You're using a very small pad.

Meguiar's UC is a SMAT product and in simple terms you can buff with short or long buffing cycles as it is not as sensitive for the need to buff long enough to break down any abrasives.

I think you're going to need a true polish and a softer pad and if you're serious about buffing out this car or any car then you should look at adding a full size DA Polisher to your tool collection and of course larger pads.

Maybe look at open cell FOAM pads instead of closed cell foam pads too like the Lake Country 5.5" Flat pads or the B&S 5.5" Flat pads or the Meguiar's 5.5" Foam discs.

All great choices.

Keep the Ult Compound and get M205. 105 CAN be a bit on the tricky side, as in...not real user friendly at times.

Remember Ult Compound is derived from 105, you can safely say, they're 'kissin' cousins'.

Likewise Ult Polish is based on M205. Originally M105/M205 were developed in the days of rotary buffers. Ult versions have been developed for DAs. But they are not apparently equivalent, at least not by this:

I don't think this has anything to do with it but when using my GG3" I have never used any speed setting other than 6. I have gone through 3 bottles of Meg's UC over the years and its always performed well for me, hope you sort things out OP!

BTW, flat, mf pads work great on the GG3" machine when doing corrections, really helps the machine keep the pad rotating AND does a much better job.
