The bondo is under the basecoat and under the clear coat, anything you apply to the surface would not interact with the bondo because, it would never come into contact with it.

That's why I said that the problem has probably always been there, it's just now, that you have noticed it. Tech wax tends to create a very clear finish enabling your eyes to see the underlying color of the basecoat. In this case, it cleared up the clear coat to such a level that now you can see the yellowing you describe.

Your question,

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??

I think I know what you're saying, but your wording is a little confusing. Allow me to re-write your question, changing it and adding a couple of words to help it make more sense.

Can you just answer this question. The reason it's not happening all over, is because the hood is the only place that has bondo on the car. So what would explain this?

(Does that read better and make better sense?)

I can't answer your question because so far, I don't' think it's the Tech Wax that is causing the problem. You claim our wax changed the color of your cars paint where the bondo is, but the Tech Wax has never come into contact with either the bondo or the white basecoat? So how could it affect it?

How many coats of clear did your painter apply? It would only take one coat of clear paint to seal the basecoat, (sprayed over the bondo), and most painters spray a minimum of 2-3 coats and in the case of a show car, more to give them some material to remove in the wet-sanding procedure and still leave plenty of film build for the future.

If your car's finish was reacting to NXT Tech Wax, (the upper surface), it would react uniformly over the entire finish, assuming it's all one type of paint. By this I mean if your painter sprayed the same brand of paint over the entire hood, (which only makes sense), then if there was a reaction with the paint, it would be over the entire surface, not in isolated areas. Problems in isolated areas sounds like something that was caused by surface prep, not something you pour out of a bottle after the fact.

This truly sounds like a problem that is under the clear coat. Of course, it's hard to say without being there to see it first hand.

Nothing else makes sense.

I understand you're merely posting what you see, but that's why I said perhaps what you're seeing now is the result from the Tech Wax making your clear coat completely clear so that you can in fact see the discoloring you say is present.

best of luck finding a fix for your situation

I agree a picture would help, but unless the difference is dramatic, it would probably be hard to capture with a camera.

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.

There is nothing that is going to get to the bondo if the car is painted... no rain water, no tree sap, no bird droppings, nothing.

That is another thing your paint also does... it not only looks good but it protects whats under it, sheet metal, bondo or what ever else is under it.

i'm going to have to agree with you i put alot of thought into this and i really do think it must have been there because nxt has made my vette white to brite white and my jeep is really sparkling like never before. but i only used one coat on the vette. so what happens if i put one more coat on the hood.

It will look shinier and have a more even high gloss, crystal clear finish.



Each car I detail with other people that are trying to learn more about detailing, I always try to pull the car out into the sun, after the first coat of wax and then again after the second coat to teach them and show them the difference.

"Two thin coats of any company's wax will almost always produce better results in both appearance and protection than one coat"

As far as any chemical reaction goes, so far, I don't think there is a chemical reaction taking place that is dis-coloring the clear coat so more coats won't have a negative effect, but will tend to make the finish more clear and glossy till the point of diminishing returns kicks in.

p.s.

I have sent a link to this thread to both Rod Kraft and Mike Pennington. Since it's a holiday weekend, I'm not sure when they'll see it but I'm sure they'll respond when they do.

did you check out the pic in gallerys the white vette

[Mike Phillips]

Now I have,



Nice looking Vette...

Mike

[Mike Phillips]

I can see the yellowing-effect along the base of the scoop...

thanks there is a pic of the front hood scoop

[6spdvette]

sorry forget my last post, so you think that was there the hole time on the hood ??

[Mike Phillips]

Did that and posted those pictures to your original thread.



I can see the yellowing-effect you're are talking about.

Just a hunch. I've seen this a lot and it may or may not be what you see. White colors yellow with impregnated dirt over time. This is a slow effect that usually goes unnoticed. A couple pictures in this thread are an example of how white paint yellows and once properly cleaned it whitens up to what it once was.

Does the yellow color you see look like the first picture and the rest of your hood look like the after picture?

If so, I'd take some MPPC by hand, or if you have a PC use MPPC or #83, and re-clean the yellowed area again and see if you can extract any stubborn grime from the paint.

I think Mike had posted a pictorial on this as well but I didn't find it in my search. Mike do you remember this? I thought you detailed a white Honda and had some pre-cleaner and post cleaner photos. Maybe I'm just having a senior brain drain.

I hate to say so without having been there before, but I have a hard time believing Tech Wax would discolor a clear coat. So yes, I think it was probably there all along, or it has recently appeared and it's just coincidence that it appeared during the same time frame you have been trying out the Tech Wax.

I spoke with a local painter on the subject of Pull-back, which I have always referred to as Die-back or shrink-back. This is when the the bondo or filling primer has dried and shrunk down smaller than the area it originally occupied causing the other layers on top of it to sink or pull-back also.

Sometimes, changes take place after the fact that are out of our control.

okay one last question and we can put this to rest. do you think i can compound this out?? if it were your car what would you do.
