"Can" would in this case mean wax can be applied without negatively affecting the paint.
Because he may be right.
It has taken a long time to get people not to change their oil every 3000 miles. The same may be true regarding convincing people not to wait 30 days (or longer) to wax their new paint.
If I have any paint questions I contact John Paterak, http://paterekbrothersinc.com
He has had about a billion dollars worth of Porsches pass through his body and paint shop over the past fifty years. Credentials that mean something.

So there should be a point in time where the clear coat is less permeable than a coat of carnauba wax. At that point there wouldn't be any off gassing of the color coat through a coat of wax. That might well be before 30 days post painting. In fact the clear coat may be finished off gassing before 30 days.
Here's a quote from the interesting article linked below:
"Many paint company now say the 30-90 day recommendations are based on old paint formulations and the p-Sheets need to be up-dated in line with the latest paint specifications, although to my knowledge this has not been done. Most paints can have a paint protection product (wax / sealant/coating) applied within 36 – 48 hours of painting."

I read through and it still states follow the manufacturer guidelines and this may require 30-90 days. Shops will polish paint w/in 24 hrs. That's fine. You can also apply a glaze right away. You just don't want to seal in the paint while it's curing. Anything placed on soft paint can/will cause damage. It's also dependent on the way the clear is mixed/sprayed. My post above covered this. If you can smell the paint, it's still curing and leave it alone.
Today, I'm sure there's many companies pushing faster times as it's geared more to production based environments. Having been around the industry for some time, I'd defer directly to the paint company or refinisher, but again, a good rule of thumb is waiting 30 days.

Well, I would have thought you were capable of reading about him yourself; his information is on the "Home" page. But I'll help you out a bit and pull a quote from there...
"With a background in the physical and chemical sciences earned a Ph.D. (Professional doctorate) and Master's degrees in Chemical Engineering and Biotechnology from Imperial College London and graduated from an MBA program with an MSc Business Administration and Strategy from the London School of Economics. He also attended Royal Air Force College (RAFC) Cranwell, graduating with the rank of Flight Lieutenant and also holds a Bachelor's of Science degrees in Architecture and Building Services from London University, England. With more than four decades in polymer R&D and the chemical and performance coatings industry for both the National Aeronautics and Space Administration (NASA) and Naval Air Systems Command (NAVAIR) utilizing polymer technologies."
I'd say he has the education and experience to be listened to.
And remember Carlo, change your oil every 3,000 miles...

"
Newly applied paint is soft, much softer than OEM paint, dehydration (drying) is a different process from cross-linking; while newly refinished paint is about 90% cured within 24 hours, even with the help of a drying oven and various additives, and will fully harden (dehydrate) after 60-90 days dependent upon local environmental conditionsThat distinctive smell of paint is actually dibutyl and diethyl phthalate out-gassing- two very volatile compoundsNew paint needs to outgas for approximately 90 days (i.e. the solvents need to evaporate) if this is hindered by an inappropriate product application the clear coat may form a 'hard film' on top and the clear coat matrix may remain 'soft'. Most product data sheets (P-Sheet) state paint will air dry in 12 hours to buff and take 16 hours to fully dry."
Emphasis mine.

l think so. Confirm with a reputable body shop. I won’t pretend to be an expert on this. If metallic material size and shape is eliminated from consideration then they only have to worry about the shade. But that is just my gut feel; no basis as I’ve never painted a single car myself.

Do as you wish. I've been in/around shops for a long enough time to think otherwise. Soft paint is too easy to damage when applying product.. He states himself defer to the paint manufacturer and as I quoted above it states cure time as 60-90 days. My first post is still the most accurate for gauging when you should apply waxes/sealants. If you can still smell it, it's still curing. It's not worth the chance of issue, just wait.

Nobody cares about oil changes either.

Oil changes are very germane to this topic.

One can easily search for dissenting opinions on the internet. Why do you search for things that discount what you read here? What about the qualifications of the people here? Carlo is right, this guy has some education, but how much real life painting experience? There's a lot of variables you discount, hence the wait approach to applying products to new finishes. Climate, temp, mixing ratio in the gun, etc. Why are you such a skeptic? There's more out there agreeing with the wait approach than of the school of thought that says wax right away. I literally just took my car from the shop last week and was advised the same from a guy who paints cars for a living. I have been taught the same all my life. I'll go with what the schooling taught me. You can read articles online. Again, defer to your own nose. You can smell the paint curing. If it still stinks, wait.
