A coat of Alclad Gloss Black primer will give a model a proper base for a shiny finish.
This was followed by Alclad White Aluminum.
I did shading with Alclad Magnesium and using a post-it note as a masking guide. While the effect turned out to be really great, I felt it was too exaggerate.
The effect was then toned down by another thin coat of White Aluminum and I think I got it just right – as the real aircraft was just plain aluminum, giving it some shading, I added a bit of interest to the plain surfaces without making things up.
