I have that same stuff Platypus, called "Bare Metal" Its not cheap, but I decided to buy it, and try it out on a P-51D model I was building.
And your right, very shinny stuff. I even tried some dull coat on a scrap peace I had. It helped alittle.
If I can ever finish that dang model I'll post pics, I was ask'n questions about finding pics for the model back in the old IL2skins forum. Gives you an idea of how long I've been work'n on it, off and on. Its one that will have almost evey door off, showing engine, guns etc. Alot of work.
But for anyone else building a metal finish model, I highly recoment it. Its uber for shure.
