Gloss Aluminium vs Gloss Grey Cast Iron

Wrap comparison · updated Aug 2026

Gloss Grey Cast Iron (#4E5151) reads darker than Gloss Aluminium (#5F5F60), so it holds shadow in the body lines where Gloss Aluminium lifts them. Both films carry a metallic finish, so the choice is purely the colour. Body shape, paint condition and the light you shoot in move both colours further than a swatch chip suggests. Seeing them on your own car settles it, free, in a couple of minutes.

Gloss Aluminium vs Gloss Grey Cast Iron: the differences.

The first difference between Gloss Aluminium and Gloss Grey Cast Iron is depth: Gloss Grey Cast Iron reads darker, so it hides body lines that Gloss Aluminium shows. The second is not the finish: both are metallic films, so the sheen is a separate decision from the colour. Low light, curved panels and your own trim decide the rest, and none of that shows up on a swatch. Render both on your car and compare them there.

Side by side

Gloss Aluminium is a wrap in the Specced catalogue, swatched at #5F5F60. It renders with a metallic finish — the sheen belongs to the film itself, so there is no separate finish to pick. Body shape, paint condition and the light you photograph in all change how it lands, so the only honest preview of Gloss Aluminium is one made from a photo of your own car.
