Water spotting after using nxt , now requiring repaint.

[Zodiac1]

I'm not sure what this proves? NXT has kept my car shiny and smooth for the past 6 or so years...so what if it burns...my car isn't on fire?

Please see the numerous references to durability of 2k such as whats on your car to Cellulose as on mine.
It proves that the solvents in NXT2 are more volatile/aggressive that Blue velvet ......maybe theres a connection

As tough as 2k is ....try placing a rag of soaked in turpentine on your bonnet and also a rag soaked in toluene ....give it a minute , take em off and you'll see what different strength solvents do for your finish.

Joking

Guys , i'm led to believe that the solvent is the same by the uk Tech guru. Either way i'm going to stick with what i know is safe.

The ultimate compound appears to be a winner for Megs tho. Very gentle yet effective on the smaller water spotting

For the roof etching on my car i had to resort to white vinegar and grey scotchbrite then hand polish with Farecla G3 then ultimate compound.

No offence taken. 15yrs detailing counts for nothing
;-). All I will say I would not be reaching for sandpaper. Least aggresive to get the job done :-) Also no paint depth gauge.? I will stick to my 15yrs experience I think!! Joking aside I hope you get the issue sorted.

I hope Mike or one of the Megs chemists can comment on your last post. I feel that although your post was interesting I doubt very much the wax is the issue. I would be interested to hear what other people think.

I would say that your paint finish has defects and the wax has highlighted it.

We still don't believe that the wax in and of itself was the issue here - we'd be seeing this sort of thing regularly if it were, and we just don't. And we probably sell more NXT 2.0 in a week than Dodo Juice sells of their entire product line in a year. That is NOT a slam against Dodo Juice. I know PJ and really like the guy, and I even happen to like their waxes. Mostly though, I love their attitude toward car care and their own sense of humor when it regards their own product lines. But Meguiar's is just enormous when it comes to volume of product moved whereas Dodo is a very tiny company relative to Meguiar's, meaning simply that we sell vastly more product than they do, and therefore have that many more opportunities to be exposed to all sorts of strange issues, different paints, different environments, etc. And we just do NOT see this sort of thing with any regularity, whether it's NXT, Gold Class, or any other wax of ours.

Unfortunately, our chief chemist is out until Thursday and I'm heading out tomorrow for Monterey and Pebble Beach and won't be back until next week Tuesday, so I can't ask him about this right now. But the strength of the solvents used in NXT is certainly not so potent that it's causing this issue. The solvents would have to be powerful enough to actually soften the paint, and for us to formulate something using such solvents would be crazy. This wax has been used countless times on older single stage paints, including original paints dating back 40 or 50 years, and again, we just aren't seeing this sort of thing happen.

Just as paint systems can vary, so can the contaminants, minerals and other deposits in rain water.


But, and this really is just as important as anything else discussed here, and in many ways even more important - if this were the first time any of you had used this or any other product, and you got these water spots for the first time ever, we certainly understand how one would think the two were directly linked. We see this all the time with all kinds of things. There's an old saying "perception is reality", and for Zodiac this was his reality. He'd never used this wax before, and he'd never had these water spots before. That isn't proof positive, however, not even close. But we understand the inclination to try and put the two together. Probably the classic example of this apparent cause and effect relationship is all those people who swear that Armor All cracked their dashboards. That is simply not going to happen - Armor All in and of itself is not the cause of that, it's not the cause of rotting tires, and there is nothing wrong with Armor All from a compatibility point of view. Looking at the sheer volume of protectants that Armor All sells - almost as much as Meguiar's sells of our entire product mix - if they were to blame for cracked dashboards then half the dashboards in America would be shot, and they just aren't.

Great post Mike. I understand Zodiac's line of thinking, but I still seriously doubt NXT is to blame.

I believe a technical explanation from a chemist is what's needed here.

Hi Mike , your post has got me thinking and made me realise that this wasn't the first time i'd had problems with a meguiars wax on this car. I had previously used Meguiars Gold class paste and had water spotting issues, though not as serious as what i've seen recently.


Could you clarify what solvent is used in nxt and gold class .....is it Naptha or similar ?

[Zodiac1]

In addition to the solvent enquiry it would be much appreciated if you could also enquire as to the Alkaline resistance of these products. I can already vouch for there resistance to acidity which is very good.

Have fun at Pebble beach and Monterey,

If necessary i'm more than happy to polish one half of my roof in Dodo juice blue velvet and the other in NXT2 and subject them to rain and sun. Though i doubt there will be sufficient paint left to work out further markings such as we've seen in this thread so it will depend on Meguiars being prepared to pay for a full repaint if rectification breaks through the topcoat?

Let me know if you'd like to take me up on the offer.

I doubt Meguiars would release that information.

Take a look at the various MSDS sheets. Maybe, just maybe that may answer some questions.

And even if you get yourself the MSDS, I doubt you'll get any concrete answers on what solvents in the NXT 2.0 that caused the water spots. Waxes, even non-meguiar ones while not the same still have some ingredients that are common to many of them.

Just noticed. Dojo juice blue velvet is a carnauba based wax (Natural): Nxt 2.0 is synthetic and is a sealant not a wax (Man made). Did you do a full Ipa wipe down clay car prior to applying Megs?.

Your test proves nothing. 2 different products a wax & a sealant. If you tried with a Megs wax I would guess the results would be the same.

I'm starting to think Megs and Dojo dont mix.
