Using UC with a DA

[bradipock]

What's the correct process for using UC with a DA? As I've read the reviews on here, some are using at higher speeds for around a minute or so, some are doing a slower speed then a higher speed, each about 30 seconds. Does either way work or is one better than the other?

I would do 3 passes moderate to heavy pressure, then lighten up gradually for the next 2 or 3 passes.

This is a very timely question. A lot of folks have now used the SMAT products, and it should be possible for Meguiar's to present detailed insdtructions on how to employ these productxs more efficiently.

I would do 3 passes moderate to heavy pressure, then lighten up gradually for the next 2 or 3 passes.

I recently read that the SMAT polishes may be best applied with consistent pressure, that the lighter passes may in fact contibute hazing.

May I suggest to the Meguiar's 3 Mike's: Please compose a good step-by-step instruction method on hos to best apply UC or SwirlX or M105 or M205. Should I prime the entier page. Whether I prime the pad or not, how many passes should I make? Should one followup one's intial regular passes with a couple of very light pressure passes? How uch product does one put on the pad after the initial passe? Etc, etc.

Cuious minds want to know ...

Your asking for a blanket use?

Every paint job is different, thus every application is different
SMAT is a "micro abrasive"
As your doing your passes you need to pay attention to the paint
Once it looks "done" your done
Does that make sense?
M105 and the like, have "diminishing abrasives", you have to break them down to the "Super Micro Abrasive" in UC and the like

Don't m105 and m205 have non diminishing abrasives? When they begin to dry out, spritz with a little water and keep polishing and they'll keep cutting. That's what I thought, anyway. I just used this combo in a test on my own vehicle and this worked for me. The m105 sample I tried was the old version which dried out rather quickly with a rotary and Meguiar's polishing pad so I spritzed, kept polishing, spritzed again, polished some more, spritzed again, polished a little more and then wiped for inspection. Did the same with m205 (although it didn't take as much spritzing) and got a nice shine with no swirls! Followed up with a light pass of D151 on DA finishing pad for quick wax application. Put a folded microfiber under DA finishing pad for removal.

Is there a list or reference indicating all Meguiar's compounds and polishes showing which have diminishing abrasives and which don't? I've been putting together my own reference in Excel with product number, name, description, use (rotary or DA, speed, pad, etc.) what grit sanding marks and defects they are recommended to remove, as well as a column for dimishing abrasives and which are body shop safe, this info would fill in some blanks for me.

Chris Dasher pulled together this list:

Here are the products that use non-diminishing abrasives:
M86, M105, M205, D151, SwirlX, Ultimate Compound, and ScratchX 2.0

Here are the products that use diminishing abrasives:
M01, M02, M04, M06, M09, M19, M80, M82, M83, M84, M85, M95, DC1, and the original ScratchX.

M105 is not a product with diminishing abrasives. M105 has the SMAT (Super-Micro Abrasive Technology) that work throughout the buffing process and does not break down while working.

Diminishing Abrasives break down while you are buffing.

Is there a list or reference indicating all Meguiar's compounds and polishes showing which have diminishing abrasives and which don't?

M105, M205, M86, D151, Ultimate Compound, SwirlX, ScratchX 2.0 are SMAT, I could be missing one

Re: Using UC with a DA

mmmm...Mike told me m105 was a DA, maybe he was refering to the older model m105? I stand corrected.

You use M105 and M205 like any other swirl remover. When working the product to remove swirls you want to have a polishing pad and be on the 5.0 Speed Setting and in most cases you want to be pushing down on the face of the pad as hard as you can while still allowing the pad to rotate at a quick pace. It should not be rotating at a snails pace.

Read through this as it applies to M105 and M205,


How To use: G110 - G220 - G100 - PC/Porter Cable - UDM
If you're moving up to machine polishing, be sure to read the below thread before starting...
Tips & Techniques for using the G110, G100, G220 and the PC Dual Action Polisher
(These are all similar tools)


The biggest difference between using SMAT and DAT products is that with SMAT product you can stop anytime during the buffing cycle because you don't have to work the product for any specific time.

With DAT product you have to work the product until all of the diminishing abrasives have broken down or you risk leaving swirls behind because the abrasives were still working.

Make sense?

Re: Using UC with a DA

I've noticed SwirlX to be very thick, and when I first applied it by hand, it would dry out very quickly. Is that an issue with the DA (causing dust i.e.?)
