Alright. So the way I do Beskar is as follows.
Black primer (duplicolor)
2K automotive clear over the black.
Chrome (Alumaluster) sprayed at about 65/75% opacity. You want more of a gun metal tone.
2K clear to seal the chrome.
Oil paints thinned with Naptha to weather.
That is a very basic overview of the process. It’s also how Legacy does it. Unfortunately this method isn’t available for a lot of hobbyists due to the cost, and health risks of the 2K. You really need a full spray booth to spray that stuff.. it’s nasty.
There are good alternatives though. For chrome, you can use Alclad products, Spaz Stix chrome, quicksilver (water based) chrome, etc. You can seal with products like Liquitex High Gloss Varnish, Aquagloss, weather with acrylics.
I spent a lot of time developing a way to put the 2K clear directly on the chrome without dulling the finish noticeably so my Beskar actually retains a little more reflectivity than is “accurate.” But I prefer it that way over how something like say the Anovos looks.
