If this thread proves anything, it is that we need Rustbucket paintjobs available in the store.
That would be so cool, especially if they looked extra scruffy with a bit of wear.
My CMDR is mostly a lowlife smuggler, miner, and mercenary, so scruffy he is. He does dabble in some legit trade, so has a shiny ship or two for this, those I keep the paint in decent repair.
But my Asp is, or at least was, the scruffiest of all my ships. I left it AFK for an hour or so and knocked it down to 45%. Might do this again later.
