Trying to polish with Megs 83 but having issues...

I'm using the 83 on a Megs foam pad with the PC. I seem to be removing the larger swirls but replacing them with smaller micro swirls.



Here is the difficulty I'm having right now. I'm using the technique from the autogeek vids (2x2 area, small line of polish around the edge of the pad, spread with pad w/machine off, then spread with machine on 3, then increase speed to 5) however the polish seems to evaporate after one pass. I find that quickly the polish is near dry. I'm wondering if this is the culprit of the micro swirls. Well that and I'm getting some dust.



It is currently 90 and with a bit of humidity. I'm working outside but in a shade.



Also, for each section, do you continue to put on as much polish on the pad as you did when it was completely dry? Or do you put a little less because the pad is already wet with polish?
 
clean the pad often (maybe even after every panel you work on). if you don't, the dried up polish will start to cake on, thus creating dusting and micromarring...
 
The dusting is just too much. Todays heat is unfortunately taking a toll on my detail. The polish seems to be drying almost immediately after I apply it the panel. Its ridiculous and a waste of time and day.
 
I find M83 works much better with a rotary, amazingly actually, but it sounds like your paint is soft and that the M83 is micromarring because its agressiveness. Have you tried m80? And you can always follow M83 with M80. And always clean your pad often.
 
83 is tricky if its hot, and your outside, so that doesnt help.



When conditions are right, i can get 83 to buff out almost clearish, dusting is minor, and it wipes off the paint with one pass.



If conditions arnt right, it fights you every step of the way.
 
Well unfortunately I'm slow and it was scorching today so I only managed to tackle the entire drivers side and rear trunk and bumper. Hopefully I can finish the rest tomorrow.



Here is what I started with...

Here is the after affect of M83...

I didn't get a close up of the M80 but it helped although there was still a wee bit of micro marring. It'll have to do for now. This is topped with NXT.

And the glorious dust of the 80/83. This was all over the windows, roof and hood. What a PITA.

As dietoremain said, I much prefer it on a rotary. Since you're working with a DA style machine, I'll see what I can offer.



What foam pad are you using? I've found that product to look its best when I use it with the Meguiar's W8000/W8006 (8" or 6"). Anything more than a touch rougher will contribute to the micromarring you see.



While you may well have some sensitive paint, M83 is past done when it dusts like your pictures show. Once it dusts, you know it's already too late to stop the micromarring from the pad. The product is long gone once it dusts, meaning you're essentially polishing dry. Dusting can also occur if you're using too much material, but usually M83 clumps and wads on the surface if you use too much. Given the conditions, I doubt that's your problem. If anything, you might be using a bit too little.



Another thing about the dust: Meguiar's does have some sort of recommendations about surface temperature for their products, but I don't know. Don't try using it in direct sunlight or on a sun-heated surface. The exact temperature escapes me, but I've used it inside shops in 90+ temps and made it work.



The heat will make it go dry much faster than normal. Is the surface at least shaded (although still in the 90 degree range)?



Be certain your pad is primed with product. No, you won't have to use quite as much after the first few 2'X2' areas since the pad should be primed. When it's this hot on your surface, use a bit more M83 than usual or do smaller areas. Pretty much any product needs to remain wet to be at peak effectiveness.



To start with a clean, dry pad, I like to put an X across the entire face of the pad. I then move the product around with my hand to try to get it on the entire pad surface.



Next, put another thinner X across the area where you did NOT have an X before. Smear that around on the paint surface with the machine off. THEN turn the machine on and do a bit smaller than 2'X2' area. M83 is done when it goes more or less clear and leaves a bit of a film. Meguiar's reps around me called the film "polishing rouge". Wipe and inspect.



Personally, if you want a micromarring/rotary mark free finish, don't expect it with M83. It's rare.



M80 looks like it helped you substantially. What pad did you use with it? M80 stays wetter longer, but it's not as stout as M83.



Overall, nice looking car. I'm sure you'll get the hang of that product if you keep adjusting your technique until you get it dialed in.
 
I'm using the W8006 pad. The car was in the shade all day but the panels still felt somewhat warm. Like I said, it was pretty hot.



I had a hard time gauging if I had too little or too much product for each application. Each time I would do a small bead around the outer rim of the pad and then spread it on the panel with the machine off. Then I continued the spread with the machine on setting 3 for a few seconds then bumped it up to 5 for the final polish to which then one pass would essentially make the polish transparent and make it appear to be already done. When this would happen I would stop and mist the pad with QD to rejuvenate the polish. I started doing this when I moved to the M80.



I'm not going to use the 83 tomorrow. The 80 did well on its own although I know my technique can use some improvement which I'm sure would make the 80 more affective.
 
I've used #80 on a PC almost exclusively for my go to polish as it tends to be more forgiving than #83. I have yet to unlock the code on using #83 via PC, so I end up taking a little more time during the polishing step of my detail to remove some of the heavier defects. I see the extra time as a wash since #80 finishes out LSP ready and I can forgo any further polishing that would be required to take out the micro-marring left by #83.

*There* it is.



Adding something other than polish to the pad isn't a good idea with Meguiar's and many others. QD or water changes the formula of the product, so to speak.



The added ingredient thins out the polishing oils. As a result, the abrasives in the polish don't get a chance to fully break down before the lubricant for them is gone. It leaves essentially unbuffered abrasive particles on the pad which will dust and cause the bad micromarring you had.



With the heat you are working in, M83 will dry faster than it normally does in 70 degree temps. I know with the rotary and 90+ temps, I only get 2-3 passes in a decent size area before it's gone clear and is ready to wipe. What I do to compensate is work a bit smaller area and change the amount of product to compensate.



I'm confident that eliminating the use of any QD or water on your polishing pad will help immensely. I'd also suggest working a bit smaller area. Even if you only do a patch or two with the product, I'm sure you'll see better results this way.

PRB, as you will notice in my statement, I say that the addition of QD to the pad was AFTER I stopped using M83. So the micro marring you see in the 2nd photo above shows only the 83 alone after working it in.



:)



But I appreciate the advice in regards to the QD mix with Megs polishes. It doesn't appear to be doing too much harm with 80. I'll see if I can go snap some pics real quick of a panel I did this morning using soley the 80 w/QD rejuvenation.
 
I had problems using a white waffle pad (with a PC) and #83 - I was working it in well and using it in the shade. When I switched to a flat white pad, the little curved scratches which resembled the PC's pattern of movemet did not reoccur.



I assume the waffle pad was trapping #83's (large by modern standards) abrasives and not breaking them down correctly.
 
Hoped I'd figured out the missing link and solved your problem



Must've misunderstood you.



So, you ran the M83, then sprayed the pad with QD...then what?
 
Try using less and working it longer. Usually, you get micromarring with a PC either because the pad/polish combo is too aggressive or the polish isn't being broken down completely. Trying bumping the speed up to 6 to fully break down the abrasives.



If the pad is still somewhat damp with product, you aren't dry buffing so don't be afraid to try buffing a little longer and see if the problem is the abrasives aren't completely broken down.

Sure. I'm using M83 via rotary in my details and I'm very pleased. No dust at all, nice cut and the microabrassives break down fast. Nice polish. :2thumbs:
