For when you want that authentic metallic finish
As one reviewer noted, the Alclad finishes do take some prep work but if you're wanting an authentic, in-scale, look to your airframe, then you should consider this metallic lacquer. It's very important to put a smooth and dark base coat down, like the black enamel base coat from Alclad, or similar, for the metallic finish to achieve it's high gloss and depth. Attached is a photo of the Airframe Aluminum lacquer I used on the engine nacelles of the Mercury 9 model kit by Pegasus Hobbies.
To hard to use for the end result but still good.
I would just use a model masters instead of this. It is way to labor intensive for the normal result. It looks great if you do all the steps correctly but the MM is way easier to use.
