Nice! Looks JUST like Sculpt-metal. I wonder if it was rebranded/reborn? It's basically a laquer-based aluminum slurry. When the laquer evaporates, it leaves a metal-like surface.
It has been years since I used Lab Metal but when I did it was really thick like a paste. I'm not sure how much it could be cut down to be used like a paint. IMHO it's not something you could use to get a fine thin finish.
My friends gave it to me when I was a kid and have used it ever since. This was after the germs but way before he was in the public eye with the Chili Peppers. Also went by Pat Fish for a little while.
