How did you apply the nxt?

How long did you let it sit before removing?

Any prep work prior to applying?

to the forum, 6spdvette.

NXT Tech Wax, unlike some carnauba, is clear and hasn't yellowed on any white vehicle I've done and I have done 5. I don't think the NXT is yellowing your hood. That said, did you remove the pervious wax prior to applying NXT. Have you tried any paint cleaner to remove the yellowing? I'd give it a go with MPPC and see if the yellow is just old wax.

i took all the old wax off then i applyed nxt let it sit for 10-15min i used a microsoaft towel. why did this happen on just the sides off my hood?? could the bondo cause a chemical reaction?? i tryed a cleaner wax clay bar nothing works

Hi 6spdvette,

Welcome to Meguiar's Online!

There is nothing in the NXT Tech Wax that will change the color of paint.

Question: Is this car clear coated? or does it have a single-stage finish?

hi, i guess it was part of the paint when they sprayed it. why did this happen where the hoodscoop was molded to the hood. can the bondo have something to do with it?? because thats the only area thats yellow. you do work for the company right. will wet sanding do it?? i tryed claying it and cleaner no good????????????????????

I have never heard of anything like this ever happening with any wax. I've seen brake fluid stain paint a different color, but not a quality car wax.

Is the paint on this Corvette a single-stage paint system, or does it have a clear coat over a base coat of white paint?

Your painter should be able to to tell you.

Don't' wet-sand the car, wet-sanding is mostly for fresh paint, not cured paint, you need to know what your getting into when you start sanding cured paint.

When you polish on the paint, does white color come off the finish and onto your polishing cloth? In other words, is this a single-stage finish or a finish with a clear coat over the white base coat?

Claying, and clay bars are for removing above surface defects, staining, or paint that has turned yellow would be an indicator of something that has permeated the surface of the paint and is now a part of the paint, not something sitting on the top of the paint.

If you don't know if your car has a clear coat or a single-stage finish, just ask your painter, he will know.

nxt and bondo???

what do you guys think can the chemicals in nxt and bondo cause a chemical reaction to turn yellowish tint on a white car.

hi, it has a base coat then clear coat.

Okay.

Now the question becomes, did NXT Tech Wax yellow the clear coat. The clear coat by definition is clear, it has no pigment.

I'm just thinking out loud now, but if NXT Tech Wax chemically altered a clear coat finish to make it yellow in one area... wouldn't it do it in all areas?

What would make one area of a clear coat finish, sprayed out of the same gun and paint pot as the rest of the car, to turn yellow, but not change the color of the clear coat paint in other areas?

I think the problem you are seeing is in the basecoat. That is, the basecoat interacted with whatever is below it, (Bondo?), and this is where the yellow coloring is coming from, not the clear coat, and definitely not caused by any wax you have applied to the surface.

I have detailed many cars in my life, and I have never seen a wax that has altered the color of a single stage finish, or dyed a clear coat another color. (I've seen brake fluid stain paint, but not a car wax).

I have also buffed out many cars where before you could not see some particular defects, but after a thorough cleaning, polishing and waxing, you have restored total clarity to the clear coat that it enabled your eyes to see the pre-existing defects that were not apparent before the detailing process.

NXT Tech Wax is safe for any paint, it's not the type of product that would stain or dye a clear coat another color. I'm pretty sure I have applied Tech Wax to more paint types than any other person on the face of the earth, (so far), and I have never seen an instance where this product would change or alter the color of paint except to make it more clear, (optical clarity).

okay i see what your saying. but my cars finish is in perfect condition i have been useing mothers for years no problems i wax over my hood no problems. i use nxt for the first time i have yellow on my hood. weather it's the base coat clear coat what ever it was not there a week ago. there has to be something in that wax that caused this. nxt wax has caused a chemical reaction with the bondo and turned it yellow. yes this sounds crazy like no way can this be possiable but it is. don't get me wrong here i love nxt i just want to get to the bottom of this. my friend has g-4 compound do you think this will work?? the next step would be to repaint.

I'll send a link to this thread to Mike Pennington and see what he has to say, our office is closed till Tuesday due to the Labor Day Holiday weekend, so it will be at least till Tuesday before he can respond.

NXT cannot affect things under the surface of the clear coat, i.e. the bondo, so my initial thoughts are this yellow coloring has always been there, its just now that you been able to detect it.

Again, if it were a chemical reaction with the clear coat, the results would be the same all over the entire finish, not in an isolated area.

okay thanks that would be fine. can you just answer this the reason it's not happening all over is because the hood is the only place that has bondo on the car. so that would explain it know??

[kromdom]

no disrespect but......

This is one of those threads when a PICTURE is absolutely necessary....hope you can post some.
best of luck finding a fix for your situation

I think the NXT would have to reach the bondo first, and that would mean permeating the paint over top of the bondo. I don't think that there is any car care product that can permeate the paint. It all just lays on top.
