Why Original Paint is so Desirable

A car is only original once.
This applies to every aspect of the car, including the paint.
Finding one that retains its original paint 20 or even 30 years later says a lot about the car, and even more about its owner.
For one, it means it’s never been in an accident. It means its been garaged most of it’s life (or all) and hasn’t been driven much. Most importantly, it means it’s been owned by a responsible and diligent individual with an impeccable desire to keep the car looking new for as long as possible.

Keep in mind that the cherry old cars you see on this site don’t just look that way because they sat untouched in a massive collection their entire life. Vehicles in this condition require a smart, patient owner (and yes, a garage to sleep in when not in use). Someone, for example, who knows how to properly wash and dry a car with care. Someone who knows how to keep the paint protected both when driving and in storage. Someone who knows to never “over detail” a car (or detail it too frequently), wearing down the paint. Possessing this kind of knowledge is more important than owning a massive climate-controlled garage, as there are big collectors out there who don’t have a clue as to how to maintain their vehicle’s paint.
You see, it’s one thing to keep a car mechanically running strong for 30 years (we applaud you). But it takes someone uniquely special to keep the original paint looking beautiful for that same period (while driving it, I might add).
Seriously, just think about how difficult that is. Someone who can buy a car new (or slightly used), drive the car, and keep the original paint looking fresh for almost 30 years.
A car that retains its original paint 20 or even 30 years later says a lot about the car, and even more about its owner.
Too many vehicles are wrongfully (or intentionally) marketed as “original paint”, hogging the spotlight from the true survivors and forcing the buyer to overpay for the wrong car. New Old Cars was founded on the dedication to put an end to this immorality, which is why I wrote the ultimate inspection guide explaining everything you need to know when confirming whether or not a car is wearing all of its original paint.
But possessing that knowledge is pretty pointless unless you understand the true value of original paint.
THE TRUE VALUE IS IN THE SCIENCE

Original paint is stronger and longer lasting than a respray. Period.
If you’re thinking of buying a car that’s been re-painted, here are some facts you should know:
– A re-paint is far less resistant to chipping and peeling.
– A re-paint will not survive as many car washes as the original paint, nor can it be machine polished as many times. This has nothing to do with thickness and everything to do with the bonded strength of the paint to withstand the machine polisher. Paint that is bonded, cured, and adhered to OEM standards will survive substantially more punishment than a respray ever could.
– The shade of color may be slightly different from factory, and the metallic flake alignment will not mimic the factory orientation.
– If a panel was replaced, it will rarely be aligned to factory specs with proper gaps.
It does not matter how pretty and shiny the re-painted finish appears – resprays are not designed to last the life of the vehicle, as opposed to the factory paint. The stringent, state of the art process at the factory’s multi-million dollar paint shops cannot be matched by your local body shop.
For these reasons, a re-paint will hurt the value of any car, whether it’s collectible or not. As a collector, you should put an incredibly high value on a car wearing all of its original paint.
Now while factory paint is by no means indestructible, its ability to withstand wear and tear is pretty incredible. As an example (assuming the paint on your car is original) go look at the road rash at the front edge of your hood. Despite the fact that stones slam into the hood at 80+ mph on the freeway, you’ll rarely find a paint chip that punctures all the way through to metal. The depth of a paint chip on original paint is usually limited by the hard factory primer, not the metal body panel.
Of course, this wouldn’t be an NOC article if we didn’t explain why a respray can’t match the strength and longevity of factory paint. To witness the complete, rigorous paint process a new car goes through, you can read our separate article on the factory paint process. Otherwise, the keys to superiority over a refinish are reflected within the images below:

Factory paint is HARD
When you have a high temperature curing process that practically melts the paint to the body (and evaporates all the water from the waterborne paint), you are left with a finish that has an incredibly high cross-link density (a simple explanation of what this is can be found here). The high cross link density means that factory paint jobs are much harder than any respray done by your local body shop. This helps explain the superior scratch and paint chip resistance over a respray.
The goal here is not to put down the refinishing industry – they do an incredible job considering what they have to work with. Unlike the manufacturer, they aren’t worried about ensuring the thinnest coat possible, nor are they under a rushed factory setting. And while this article emphasizes strength and longevity, most body shops who put the time in are easily capable of producing a far more beautiful finish than what comes out of the factory. Unfortunately, many insurance repairs don’t see this level of dedication, and the quality shows.
In the end, the goal is to shine a brighter spotlight on the cars wearing their original paint. It’s a guarantee – not a gamble – that a re-painted car will chip easier, offer less scratch resistance, and wear at a faster rate than the factory paint job ever could. So, collectors – you aren’t just chasing the factory finish for its originality – you are after it’s strength, uniformity, and longevity.

About the Author: Andre Clemente, a member of the Society of Automotive Historians (SAH), has spent over 12 years in the business of buying and selling cars – half of those years were dedicated to the classic car/sports car business. As an automotive paint fanatic, Andre has been hyper-focused on learning paint correction and inspecting automotive paintwork, working alongside veteran dealers, brokers, and a licensed Concours judge in the process. Years of real-world practice and application gave him the experience to identify inaccuracies and myths that are widely accepted when authenticating a vehicle’s paint job. Rather than keep his knowledge as a trade secret, he has decided to share the research and insider details he’s learned to help educate the collector car community, and ultimately shine a brighter light on the cars truly wearing their original paint.
