    I have rust spots like this

    I used this pad, fairly agressively!

    And all the more I could get to come off was like this

    I'm not wanting perfect but is there a good grinding disk I can use to knock this off without removing too much metal. I plan on repainting but I'm not to worried about flat spots.

    I used a disk just like that one to do bodywork on mine, not rust, just to grind down weld i put on, it worked good, just grind it down to just below factory body metal line, and then glaze it with either bondo or glazing putty... just my 2 cents.

    I think that by the time you get rid of the rust there will be no metal left. I would cut it out and weld in a patch. Other than that just go buy a more aggresive grit disc.

    looks like somebody doesn't have to work today /forums/images/graemlins/rolleyes.gif

    try a DA sander with an 80 grit pad.

    Actually...it needs sandblasting!!
    If you don't remove the rust from inside the pits...
    it will be back!!!

    If blasting isn't possible....
    I'd hit-it with #40 grit grinding disks....
    dent-it in a little....
    then apply some duraglass over it.... /forums/images/graemlins/smile.gif
