Powder coating
or paint?

For alloy wheels, powder wins almost every time. The exceptions are real though, and knowing them stops you asking for the wrong one.

Both put a coloured layer on a wheel. The difference is how it gets there and how hard it ends up, and on something that spends its life being hit by stones and salt, hardness matters more than almost anything else.

How they differ

Wet paint is sprayed on as a liquid and dries by evaporation. Powder is applied dry as electrostatically charged particles, then baked at around 200°C so it melts and flows into a continuous film.

That baking is the whole difference. A cured powder coating is substantially thicker and harder than an air-dried paint, which is why it survives stone chips and winter salt far better.

The short version

Powder is baked, paint is dried. On a wheel, baked wins.

Where powder is the right answer

Any standard single-colour wheel, gloss, satin or matt.
Anything that lives outside on the coast or does winter miles.
Colour changes, where durability matters more than an exact factory match.
Fleet and lease work, where the wheel needs to survive several drivers.

That covers the large majority of what comes through the unit.

Where paint still wins

Some factory finishes are multi-stage — a base coat with a tinted lacquer over it, or a pearlescent that shifts in the light. Those cannot be reproduced in powder, and trying gets you something close but visibly not right.

If you are refinishing two wheels out of four and the other two are staying, an exact match matters more than durability. That is the strongest argument for wet paint there is.

And diamond-cut faces are neither: they are machined metal under clear lacquer. Neither powder nor colour goes on the face at all. That is covered on the diamond cutting page.

What to ask for

Honestly, do not ask for either. Tell us what the wheels are, what finish they have now and what you want them to look like, and we will tell you which process gets you there.

The one thing worth specifying is gloss level. Gloss, satin and matt behave differently and matt in particular shows surface imperfections, which changes how much preparation a tired wheel needs.

Either way, the preparation underneath matters more than the choice between them. A badly prepared powder coat fails faster than a well prepared paint.
