Dead Paint

Dead Paint is a term of art used to describe paint which has become oxidized. This is caused by interaction with the air and ground level ozone. Water and UV radiation can also play a part in this process.

It will result in a slightly hazy/milky finish on your car, which is often barely noticeable. However, the paintwork is duller than it could be and once you polish it you can see the difference.

There are other things that can cause dead paint, such as strong chemicals, acid rain, which might burn your paintwork, but in general it's caused by oxidation. Thankfully, because it is just on the surface of your paintwork where it contacts the environment, it generally doesn't run deep, meaning it can be polished off fairly easily.

What it means

Dead paint is paint that has gone past normal fading and oxidation. The surface has dried out, oxidised and broken down so badly that it looks flat, powdery and lifeless. On older single-stage paints (where colour and gloss are in one layer) this often shows as chalky red turning pink and then almost white, or dark colours going dull and grey. On clearcoated cars you can see hazy, milky patches and areas where the clear has little life left and may be close to failure.

Why it matters

• Very limited material left to work with: Dead paint is often thin and fragile. Aggressive machine polishing or sanding can quickly break through to primer or metal.
• Cannot always be fully restored: Light oxidation can often be brought back, but truly dead paint has lost so much binder and pigment that the best you can do is improve it, not make it like new.
• Shows underlying neglect: Dead paint usually means years of strong sun, weather and little or no protection, which may hint at similar neglect elsewhere on the car.
• Helps choose between polishing and repainting: Identifying paint as “dead” is a clue that repair and repaint may be more sensible than spending hours trying to polish life back into a failing finish.

Where you’ll see it

You will see the term dead paint used on inspection reports, detailing estimates and classic car appraisals. Typical comments include red paint dead on roof and bonnet, dead single-stage paint or lacquer gone dead on upper surfaces. It is most common on older cars, flat reds and blues, commercial vehicles and anything that has lived outside for years without protection.

Context

Dead paint sits at the extreme end of oxidation and fading. Detailers will often do a small test patch with compound and a machine polisher to see how much gloss can be safely recovered. Sometimes there is enough sound material underneath the chalky surface to make a worthwhile improvement. Other times the paint powders badly, shows very low readings on a paint depth gauge or reveals early clearcoat failure, at which point the conversation usually turns towards repair and repaint. Protection with wax, sealant or ceramic coating is still recommended after any improvement, but it cannot rebuild paint that has already died.

Common mistakes

• Promising to “restore” completely dead paint to like-new when there is simply not enough sound material left.
• Attacking dead paint with very aggressive compounds or sandpaper without checking thickness, leading to burn-through and exposed primer or metal.
• Judging success only by how good a small test patch looks when freshly polished, without considering how quickly a weakened, dead finish may dull back down.
• Skipping protection after improving dead paint, allowing the newly exposed surface to degrade even faster than before.
