I should add I've just been told its only acrylic paint with no clear. At least that's what my clients been told

From the photos it does look like normal paint oxidation, yes..

Here's a few articles that will help...

Looks like oxidation to me too.
Mike has a great article on using Meguiar's #7 Mirror Glaze on what I call dry paint.
I'd work the polish in by hand, let it sit over night then buff off, see if it does anything.
Then I'd start with something like Meguiar's 205 Ultra Fine Polish using a white pad but only doing a small test spot to see if you get results.
You could try working a small spot by hand just to be safe but in the end I don't think you can cause more damage using a light polish.

ok thanks for the tips guys.

I read the write up using #7, will have to give that a go!

In the second picture where you can see a line/edge/border where the paint is a different color and it looks like a rash that's not oxidation that's a physical problem with the paint separating one layer of paint from a previous layer of paint, at least that's what it looks like from the picture.

I tried to draw some black lines following where I see a flaky or jagged edge of something wrong going on with the paint.

The #7 might even out the color differences as that's one of the things the oils in #7 does, it brings out and restores the full richness of color in the pigments.

But the jagged or flaky edge is a different issue. I would try troubleshoot by hand polishing with a light or fine cut polish over a section the jagged looking edge and see if you can "affect" it, that is make the problem go away.


My guess is this is one layer of paint coming off the underlying layer of paint and the more you polish on the flaky or jagged edge the more it's going to recede in one direction or the other.

Just a guess by the picture...

Once again thanks for the replies everybody, AG's the best :)

Do keep us updated and remember, if the problem is as I've described, polishing with the #7 and then sealing with a quality wax will "help" to even out the appearance then the owner should repeat this process often to maintain it.

Single stage paints need regular polishing with a product like the #7 to endure over time.

I just answered an e-mail from a guy that saw me restore the paint on Wayne Carini's original paint 1953 Hudson Hornet. This guy is working on the original paint on a 1955 Corvette and I told him pretty much the same thing, that is rub the old paint down with #7 and a cotton, terrycloth wash cloth to remove oxidation, re-polish using a foam pad for regular maintenance and the seal with a quality Carnauba wax like Pinnacle Souveran Paste Wax and you will be doing everything possible to enable the single state paint to both look good and last a long time.

Remember to share AGO with all your car buddies, that's called win/win

Meguiar's #7 Show Car Glaze (http://www.autogeek.net/meg7showcarg.html) is a tried and trued product and has been around for as long as I can remember so that's a good long time.

Old #7 has been a long time favorite of show car buffs as it's oils leaves the finish wet looking. #7 also contains fillers that do a great job at filling minor surface imperfections..

The only downside is Meguiar's #7 doesn't provide anyprotection so once it dries and it's buffed to your satisfaction, apply a sealant or wax to give that shine some durability and protection.
