Issues with M95... *pictures inside*

Well I decided to grab some M95 that I had around for a while, I honestly used it once or twice maybe a year and 1/2 ago... and I kept having an issue with it...



Products I was using:

DeWalt Rotary at 1500 then 1400rpms

Meguiars #95

Polishing Pad (about 3 uses on it)

Microfiber Cloth

Foam pad spur



I was applying the medium directly onto the pad, first doing two quarter sized drops, would place the pad flat on the surface, pull the trigger on the dewalt rotary and immediately begin moving across the surface at 1 inch per second. I kept having this immediate buildup of material that would harden to the surface the instant I would start polishing, it would not come off after making a pass over it with the rotary, and I mean within a second of me starting polishing it would harden, I would go over it, and it wouldnt go away, and I have no idea why... I spurred the pad after every pass. So I tried a couple different things...



First - I put ONE quarter sized drop instead of two.. still did it.

Second - I set the RPMs from 1500 to 1400 and it still did it.

Third - I would slowly start polishing by progressively pulling the trigger harder, so it wouldnt instantly spin at 1400rpms.... still did it.

Fourth - I tried applying the medium directly to the surface... still did it.



Thinking it was me... I tried using Menzerna 106FF and worked perfectly, applied with two small drops directly to the pad, worked a 2' x 2' section until it flashed, and polished the surface.



What in the world is up with M95? Is M105 as difficult to use as this stuff? If so, Im staying away... what a nightmare.



PICS:











 
Did you try it with any other pad? Was it goofy temperature or humidty?



I just used M95 today with a flat LC orange pad with no problems. I primed with 4 1.5 inch lines about a half inch in from the edge, then a small dot in the center.



I smeared on the working section (~18x18), spread very quickly at 600 then jumped right to work at 1500-1800 finishing as it started to clear out at about 1200. What if you tried something in the neighborhood of 1000-1200 and added a little pressure?



If it makes you feel any better there was a day about 2 weeks ago where just about everything I owned appropriate for a 1 step was acting up ridiculously on all machines and just about every pad. It took at least an hour to find a combination that I could get by with. I have never experienced such a frustrating polishing situation.. And wouldn't you know it, on the very last section my chosen selection worked PERFECT..
 
I have had that happen with M105 and M85. I just took a little more compund to it and it went away. I have had it happen more with the M105 but I think that it was the way that I was applying it at first. The last few times that I have used it it has been fine, but I also changed the way I was using it.
 
There is something on the paint that is causing your polish to flash. Really strange, since 95 doesn't like to flash.



One of the reasons to do a thorough IPA wipe before polishing is to make sure the paint is completely stripped of anything that could afferct the polishing process. Remnants of old LSP are the worst, especially if it doesn't evenly cover the panel you're working on. Typically, you'll be polishing along, and suddenly your rotary starts bogging down, then next thing you know, you're looking at a "skid mark" of thick, dried on polish on the paint that is then hard to remove. You just ran over a patch of old LSP.



Some guys think, "ah, I'll just *polish* my way through that old LSP!" David Fermani has said (amd I believe him cause I've tried it :) ) that many times, you will *not* be able to grind your way through old LSP's with a polish, and that they must be chemically removed.



Anytime your polish doesn't behave the way it should, immediately suspect two things: 1. There's something on the paint that is messing with the polish. 2. You need to shake the polish up much more.



Edit: the original formula M105 behaves much as you describe; it flashes over very quickly. The new formula *can* flash fast, especially if you pre-spread it, but typically gives more working time than the original formula.



M95 should work just like a traditional polish; apply, pre-spread, work until clear, remove. It's about one of the very easiest compounds to use. What color is your M95? I'm wondering if you got slipped some 105. Here's what they look like...

Yes the M95 I was using was a tanish color, so that is correct.



There are several people that were telling me that it seems something must have been on the paint... but it was weird, when I tried the Menzerna, it worked perfectly? Hm... I dunno.



And how are you pre-spreading the polish? Using the pad to spot it around the 2x2 area, or applying directly from the bottle onto the surface? Which one works best?

it was hot as hell, and just rained, so very very humid in the shop..

Which Menzerna product?

106FF always polishes smoothly, even on contaminated paint. Perhaps this is due to the fact that it's got so much more lubricants compared to a heavy compound, being a very gentle polish itself. I'll bet that if you try this with Menzerna powergloss, you will have an even harder time than you area already having.
 
I think the 3 most probable causes have been sufficiently covered by Supe and Getcha. But whenever I’ve had this happen, one of the following has always remedied the situation:

1) More thorough stripping of LSP

2) Better mixing of product (IMO insufficient mixing tends to affect Meguiar’s polishes more so than Menzernas)

3) Adjust temp/humidty or add more lubricant (drop or two of OP/UF)
