Hi. I made a post a week or two ago, but now I have a picture. The hood of my car is oxidized and I used Klasse AIO on it and it dissappeared for about 3 weeks and then it came back. Is there any way I can get rid of this or will it keep coming back? Heres the pic.
 
What did you use besides AIO? I assume you at least used a wax or sealant on top of it.

Just AIO. I was going to put wax on it but then it started coming back so I didn't.
 
I believe that paint is single stage. I would use ColorX to remove the oxidation + it gives it some protection and then top it with a long lasting LSP.

Do you think it is single stage on just the hood or the whole car? I am pretty sure its the original BC/CC from 1991.
 
When you polished it initially, did red paint come off? If so, then it is SS, if not it is BC/CC?. My Dad had an earlier Fox body Mustang with SS
 
By the looks of that, I would say you will need something stronger than Klasse AIO, possibly a compound.

Were you applying the AIO by hand or machine? :buffing:
 
If the AIO removed the oxidation, then you've got that covered. You just need to apply a LSP product on top of it. That should keep the fading from coming back.
 
If it is bc/cc then you are going to need to cut it and polish it to remove the oxidation. If its ss you may want to try megs 7 followed by a good sealant.
 
I hate to tell you this but either way clear coat or single stage if it oxidied that quickly after polishing the clearcoat has probably failed or if single stage the pigment in the paint is probably dead and not repairable by buffing .

But it wouldnt hurt anything to try buffing with a more aggressive polish or compound just dont expect miracles and sometimes you do get lucky.

Good luck!
 
Here's a 1974 BMW 2002 that had been repainted in 1981. This car's paint was VERY oxidized and rarely (if ever) waxed before my polishing.

I measured the paint thickness before polishing and used Menzerna Power Finish followed by Jetseal 109 sealant. Orange buffing pad used ....... paint thickness was 4.3 + all around the car.

Even old & oxidized paint can be saved more times than not.

Gotta disagree here. The fact that he's already corrected it shows that the problem is not that far along.

I think the problem is real simple. He cleaned it up with AIO and apparently had it looking good, but he didn't put anything else on it, so the changes weren't protected and it got oxidized again. If he uses the AIO again but drops a sealant or carnuba on it, I bet that solves the problem.

i understand what your saying , but klassee is a sealant and does offer protection ......so that is exactly why i think the paint is failing.
 
Thanks for your help guys. I'm gonna try and polish it and put some wax on it tomorrow. I'm pretty sure that the hood IS single stage, but I think the rest of the car is clearcoated, so I don't know whats going on there. It looks like the hood has some bondo on it, so maybe it was repainted with SS at one point? I will see tomorrow though. Thanks again.

The sealant is a different product.

Klasse High Gloss Sealant Glaze, klasse SG sealant, klasse sealant glase,klasse sealant

Yes i know that .....Jeff used the klassee AIO and it is an acrylic sealant and polish

"" Klasse All In One is a non-abrasive polish that will remove oxidation, old wax, bug smear, and some fine swirls, scratches and tar. This step will really brighten the paint and really make it "pop" again. While it cleans the paint's surface it also leaves valuable protection from its specially formulated acrylic coating. Klasse All In One is a sealant that is extremely durable and will protect your paint for months to come. It will protect far longer than natural waxes against fading from the sun, moisture, oxidation, salt water, pollution, bug smear, and other build ups""

Well time will tell after Jeff polishes it . The single stage reds in paticular are prone to oxidize to point of no return.

But hey i really WANT to be wrong about this and maybe i am :)

Completely possible the hood has different paint than the rest of the car...

Real simple test... take some AIO, which is a Cleaner/Wax or Cleaner/Sealant for the D.O., and rub some on the hood with a white cloth and then turn the cloth over and look at it.

If you see gobs of red pigment coming off you're working on a single stage paint, if you see the color of the AIO and the cloth then you're working on a basecoat/clearcoat.

If you're working on a bc/cc then that paint has failed... and it's past the point of no return...

If it's a single stage paint and it's turning white after you polish it with the AIO then there's a chance you might be able to save it with a pure polish from the old days... like #7 Show Car Glaze from Meguiar's.

Something about the "oil base" used in #7 that can work miracles on single stage paint. You can find these same oils in #3, #5, #9, #81, #45, and Deep Crystal Polish, if it is single stage, get your hands on one of the above, and rub out half the hood with it and see what it does for the color.

THEN... allow a few days to go by and see what happens... if polishing with a pure polish restores the color BUT the results don't last over time, then the paint has become "Unstable".

Once a single stage paint becomes unstable it's past the point of no return.

Correct, it's a cleaner/sealant, in the normal world the term Cleaner/Wax is generic name for a category for paint protectant that also clean and even abrade the paint, this features dramatically separates them from finishing waxes or show car waxes like Souveran Paste Wax which has no cleaning ability.

What Klasse AIO doesn't have are they polishing oils like the #7 has which are unique to Meguiar's, (to my knowledge).

These oils penetrate into single stage paints and restore and revitalize the color. A product that primarily cleans and protects, but is missing these oils, won't have the same effect on a single stage paint.

I never like telling someone their paint is past the point of no return...

I wonder how the hood is going now?


Mike l I had forgotten i was able to save a red porche several years ago after using #7. The red paint did not respond to polishing so I though the paint was dead but starting to mess around with different products and the #7 completely revialized it .

I told the owner I did not know if it would last but year later he said it still looked fine . I was so surprized and pleased!

I was thinking more about the klassee and Ive used it on single stage paint and not been very happy with the results. It really only has a mild polishing ability so Im really hoping this red hood just needed more aggressive polish to get off the oxidized layer.

Im feeling much more hopeful for the outcome of this hood now. Please let us know how its going!
