Single stage Concour paint issues

[tferrer]

I have a show 65 Jaguar E-Type that has what I believe to be a 8-12 yo single stage paint job done to a very high level. There were very light scratches on the bonnet that I thought I could buff out so I tried Menzerna SF4500 with a black LC finishing pad. The scratches were visibly reduced after 5-6 passes but now there are about 10-15 very small, pinprick size spots which look to be down to the metal! You can actually feel the small indentation. I would have thought there would be a primer level between but this looks like bare metal. My question is, how best can I minimize the visual effects and protect the finish? Would a Dr Colorchip work? The spots are very small so might be difficult to work paint into such a small area. Help!

You are going to have to post some pics so members of the forum can see what is going on to help.:xyxthumbs:

Pics would help.If it's so small that you have to look for it leave it alone.how do you know it's single stage are you getting color on you're pad.youre main goal was to minimized the scratches which had to be light cause of the combo you used.Dr color chip will probably make it worse being that it's not a factory paint job ,so color matching wouldn't be a option.Sounds to me there was a spot repair done there.ive never heard the term high level single stage,are you implying it's dust and nib free.Youre only alternative is to just wing it and hope they don't see it,or get it fixed before which maybe a long shot before the show,is it a xrayvision car show where there are points involved ,or just a cruiser show

Here is a pic of a couple of the larger spots. From more than 5 feet, they are very hard to notice but the silver metal is quite apparent when you get a bit closer. It's a JCNA judged car so this wasn't really nice to see happen.

Here is a link to a picture:

What do you guys think?

Mike: you have any idea what could have gone wrong and what my next corrective step might be?

Forgot to answer your question re how I know it's single stage. Because color is present on pads and MF cloth with any buffing. It's definitely single stage. If I had a paint meter, I could give you a thickness but alas I don't. Based on these spots, it looks thin.

On a high resolution iPad I still can't see it .If there are actual holes.u can't make you're promblem go away with wax.did they repaint the car according to factory paint code ,if the painter mixed it pretty close ,then dr chip might work ,or better yet take car to a paint supply store let them scan the paint .they might be able to match 98 percent ,it won't be cheap I would get a pint of touch up.

Other than very gross and obvious defects, internet diagnosis via photos can seldom be conclusive. With that said here's a possibility... Could those spots be some foreign contaminant embedded in the paint during refinishing and then exposed, or uncovered, during polishing?

Before you attempt any repair consider this... As hard as it may be to accept this fact, many minor defects are better off left alone. Often the repair looks worse than the original defect.

As for color matching, regardless of whether or not this is an original factory color, perfect matches are hard to come by. Simply having a paint code and formula for a specific color does not guarantee a perfect match.

It gets it pretty close once they scan is paint not the paint code he was looking for a quick fix before the show ,and these are the possibility .just paint hood and fix it ,I don't understand after all this time and u see it now.

Thanks everyone. The repaint is very close to the factory Carmen Red. I have a custom formula for something very close but it's not perfect. The paint is fairly old so I can't believe that its never been polished. It DOES look like something in the paint during the refinish. Looks like it was a pre-existing condition and had been "hidden" by some method like a Dr ColorChip or Zymol Rouge when I purchased the car in January. I've gotten a quote to have the center section repainted and cleared. Not cheap but it is a show car. Red is hard to match so yes, I'm taking a chance and might be better just leaving it alone or perhaps trying something with less associated risk like Zymol Rouge wax. At least its not going to damage anything. Anyone tried the Zymol Rouge for single stage paints?

Do you know if the repaint, using a BC/CC paint
system, will have any adverse affects on the vehicle's:
"Evaluation and Deductions"...in the Class
you're going to enter it in?

Even at many Concours events, where they have
a "Preservation Class"...points are deducted for:
restored/reconditioned items that are non-authentic,
wrong, missing, or incorrect.

I'll suggest to first call the national branch
of the JCNA to get an official pre-Show ruling
before proceeding with any further repairs.

Good Luck!

Yes I've seen little dents,and horrific outcomes when it comes to a simple repair,I was a victim of that ,agreed if it's so minor leave it,you're asking for promblems ,unless you're retired lol.I haven't used symbol in year sorry .

now there are about 10-15 very small, pinprick size spots which look to be down to the metal!





I've been seeing and answering this question in the forum world for about 13 years now, this is just a guess but sounds like what I've seen as you describe.

From this article I wrote back in 2010.... after teaching a guy that had NEVER machine polished paint how to machine polish BLACK paint on a Porsche....


Proof You Can Do It! - Joe The Detailer - Black Porsche Turned into Black Pearl! (http://www.autogeekonline.net/forum/show-n-shine/25226-proof-you-can-do-joe-detailer-black-porsche-turned-into-black-pearl.html)


Here's the car....

Here's BEFORE

Here's a side-by-side... NOTE how the swirls and scratches are GONE on the after side but now you can see TINY LITTLE PIN PRICK HOLES in the paint?

And after all the polishing and waxing, you can still see them with the flash of my camera....

And even though these pictures were uploaded to the AGO gallery 5 years ago they have not disappeared like most pictures uploaded to Photobucket 5 years ago.


:laughing: :Picture:



Let me know if that's what you're seeing tferrer


And... if it were me I would machine wax and move on. I've never seen these types of tiny pin hole defects removed by more and more buffing. The defects remain and you get thiner and thinner paint.

Also, in the real world, you won't see them, that is when the car is on display under natural light.

And for what it's worth... I never saw Joe again... just another guy I taught to machine polish paint over the decades.

Thanks for the response, Mike.

I'd have to say, theres a pretty close match on what you saw with that Porsche. In your pics, the spots are more numbered and uniform but they do look like they are down to metal/primer, though. Mine is single stage and there are no more than 15 small spots which are really small "craters"down to bare metal (unless the primer was gray). There a few that are larger than others but most of them are small. At this point, I'll follow your sound advice and not manipulate the areas in any way through buffing etc. I've ordered Sonax Nano Red wax to at least try to get some color "into" the areas that show silver. I'll report back and give an update. Thanks for everyones comments!
