    While I have my engine out I am going to repaint the driverside fenderwell that was damaged by a leaking Master cylinder.
    How should I go about cleaning prepping the surface to make sure the new paint adheres ?

    We swapped dad's cuda to dot 5 after a spill with the old style fluid.
    Sorry not much help with prep work.

    You would go about it the same way you would any surface getting ready for paint.
    Clean it with Lacquer thinner or something similar, sand, primer, sand and paint.

    I had a fender primered sanded and ready for paint that was in my shed so nothing would get on it.
    There was a weed eater I put up in the rafters to make room for the fender and it dripped gas/oil on about a 1 foot area overnight.
    Pissed me off man. :D
    I went out in the morning to get it set up for paint and had a nice oily goo spot.

    It did turn out ok after it was finally done.

      use b-12 carb clener and a shop rag and just scub away, be carefull about getting it on any existing good paint though because its pretty volatile stuff

        I understood brake fluid to be more pervasive than other fluids and have some lingering effects if not treated properly.

        Not that I have ever seen or dealt with, as it needs to be cleaned up just as if it were oil.
        You could hit that spot with self etching primer once clean just for a little peace of mind.

        Yep, pretty much any good strong solvent works well for that kind of stuff.
        I like lacquer thinner because it dries up really fast, but so does the b12.

          Good soapy hot water will clean it good for a start, then prep it and prime it.
          Brake fluid is water soluble.
