    I'm trying to replace the donut gasket on our 2008 Pontiac Vibe
    (rebadged Toyota Matrix) -- the donut at the connection between the pipe connected to the resonator and the pipe connected to the muffler.

    I've scraped and chipped away a lot of black and grey stuff, but there
    are still lumps in places, and in other places something with a regular cross-hatched appearance that looks as though it might have been the
    outermost layer of the original donut.

    Do I have to get down to bare shiny metal? If so, is there an an
    alternative to just chipping away and wire-brushing or using a
    small-enough drum sander?


    The muffler and pipe are off the vehicle, so I could even use a propane
    torch if it would help.
