Best way to separate pinch welds

The belt sanders are worth their weight in gold imo. Plus you can get the belts in scotch brite form for removing seam sealers and other stuff. Ive used the crap out of mine. But spot weld bits are just as effective

I agree, I use a dynabrade. Not budget friendly but its light years better than the china ones. Made in the USA and the quality is amazing.
