Gloss Aluminium vs Gloss Grey Cast Iron

Covering comparison · updated août 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.
