Re: Water spotting after using nxt , now requiring repaint.

I shared this with a friend that has a loooong history in the automotive industry. His reply is below....

Good information Chad.

Thank you...

Re: Water spotting after using nxt , now requiring repaint.

I have the SAME EXACT problem as you dude!!! I polished my car with a marine wax (Meguiar's) and since then, I have the SAME water spots has you at EVERY rain and it's pissing me off really hard. They won't go away until I use WD-40 or Jig-A-Loo. I really need to find a way to remove them... Hope we can find some help, cause you can't know how much it ***** to have these spots...

Hmmm....I don't know if this is the correct question to ask but...WHY are you using a Marine Wax on your car? Secondly...WHY are you using WD-40 on your paint? These two things I don't believe belong on an automotive paint job....

Because I read on this forum that the Marine Wax was not supposed to do any damage on the paint (and I searched A LOT to know if it was going to damage the paint) and the WD-40 is the only stuff that can get rid of these nasty water spots. BTW, since I "washed" my hood with the WD-40, there is no more water spots! It won't last long, but I'll do a couple of pass with a quality wax.

Of course, the offers there. Just need Zodiac to get in touch.

Re: Water spotting after using nxt , now requiring repaint.

Hi Everyone just thought i'd give a quick update as things stand at the moment.

Firstly and with sincere gratitude for the offer of sorting my car out i would like to thank Rapport, However and i mean this with the greatest of respect to the guy i am very capable of sorting the mess and will post pics of the finished article.

Thanks again tho , it was a very kind offer and had i not had 26 years in the trade i would have bitten your hand off.

Secondly my original point regarding the problem of baked in calcium/mineral spots when using NXT2 as opposed to Dodo juice Blue Velvet ( which unfortunately i had run out of ) has led me to investigate this problem further.

In my opinion ( and as i have said from the start of this thread ) i believe NXT2 was unsuitable for my cellulose paint and has exacerbated the normal unstable nature of the paint ( made softer ) due to the volatile / aggressive solvent used in it and this has made the paint more prone to etching of calcium/mineral marks. particularly for those in hard water areas such as myself.

I'm sure were all familiar with the word petroleum distillates in waxes but how many of us realize that those petroleum distillate solvents can vary in strength....in the same way that paint can have an aggressive basecoat solvent and 1k synthetic will have a weaker solvent very similar to oily white spirit.

I am aware that all waxes carry solvents but it is the aggressiveness ( hopefully lack of ) Quality and suitability for my type of finish that i have called into question with NXT2.

Its worth pointing that out that on a hard durable 2K finish an aggressive solvent based wax can assist in creating a lustrous shine and vibrant colour without softening the paint or lacquer surface.

Ok so how volatile and aggressive is the solvent in NXT2 , yes i know it has a warning of combustion on it but just HOW aggressive and combustible is it when compared to Dodo juice blue velvet. The very wax i had been using prior to NXT2 with no mineral etching.

Lets set fire to a small amount of each and see.

Firstly the NXT2.



Instant combustion.



Now tho Dodo juice Blue velvet ( my last scrapings ).



















Try as i did the Dodo would not burn and once solidified was good to use again, unlike the NXT2

I'm not trying to stir up a hornets nest here and hope it isn't percieved that way.

Me , i'm going to keep the heavy combustibles in the fuel tank ......certainly where my paint type is concerned.

Re: Water spotting after using nxt , now requiring repaint.

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?

Re: Water spotting after using nxt , now requiring repaint.

That looks like NXT 2.0 in paste form. I wonder how liquid form would do under that test as there's no flammable warning on that version. Maybe NXT 2.0 in liquid would be more suited for your paint? Just a thought...

Interesting test, and good point about the NXT liquid vs the paste.

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.

Re: Water spotting after using nxt , now requiring repaint.

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.

Re: Water spotting after using nxt , now requiring repaint.

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 ?
