    I too use the flap wheel disc on a 41/2" grinder. It smooths out welds and does not leave gouge marks in the metal. They come in different grits depending on how much metal you need to remove.

    also remember to only remove the weld not the material around it.

    I like the flapwheels, but with any grinding on sheet metal move around quite a bit too much heat in one place will create distortion and warpage that just wont go away, larger panels are the worst but I've seen patches in rockers ground too fast and cause distortion. Just take off a thin layer at a pass and make long smooth passes, removing material at an even rate hence heat input will be at the same rate and warpage will be minamized.

    Good luck,

    Grinding weld beads

    Hi again guys,,got my new MM251 and love it
    My question is what are you all using to grind down the weld beads on sheet metal?
    What is the best way to grind the sheet metal to ready it for paint?
    I am sure some of you have some trade secrets
    Thanks again
