uncoated/just polished - they have this stuff here in America called "elbow grease" :lol:
that - combined with a little polish and she peerks right up - but your right they do scratch easily and require a little care, we'll see what it looks like in a yr or so...
I had the privilege of taking a seminar from Evan. What a great and humble guy.
When the tank is done, Evan finishes the surface down to 600 grit paper and then polishes with Simichrome. Evan brought in a tank he made for a Moto Guzzi. It lives in San Francisco and is ridden often. The sparkley shine came back with very little effort. You couldn't find the spots Evan repaired.
