Rust Killer,anyone - Updated job done/ Not done

[vinnyb]

Looking good sharpie. Just had a good old poke around underneath mine and it's still totally solid and the studs look rust free too :thumbup  but I'm not taking any chances when I remove it. Just wondering whether there's anything I can do while it's off, to prevent it rusting from the inside, I thought of maybe cleaning it out a bit with brake cleaner then squirting a load of VHT paint down the end, (obviously with the silencer removed) and swilling it around in the hope that some of it might stick around the balance tubes and collector box area then pour out what's left. Opinions please. It's got to come off anyway, along with the radiator, cos I need to repaint the front of the engine and touch up the frame brace bars. Never endin' innit?
