Duster has gone "under the knife!!"

I used the Blair's and others...The Blairs stayed sharper but, I think they are made of a more brittle material tending to break more often. I found the easiest thing to to is center punch the weld best you can. Use a small unibit drill. Drill down till you have a good center. Then take an angle grinder and smooth area best you can, close to flat. If you use the spot weld cutter on an awkward spot thats not flat they have a tendency to snap. Drilling squarely in to the weld makes it for better drill life. Dont be afraid to use a hammer to get it flat...
