Spot Weld Removal

I have done the same thing drill what you see, then seperate panels where you can with a screw driver or chisel this will help to locate the ones you couldn't see. To uncover the spotwelds I used a nylon bristle drill attachment that has a grit engrained in each bristle. I stripped down to bare metal with this and was able to detect almost all of the welds. It workd great strips faster then a wire brush attachment without any scratching.
