We use a belt sander, run it across at an angle, then back across at the opposite angle. You can also use an orbital sander/polisher. Harbor Freight sells a 7" pretty reasonable. Hope this helps. Joe

Try the sander/polisher. I think a grinder is to fast. If you're gonna try something different.

We used a grinder 8 inch and 4 inch .
Its all in the technique.
You can burn a spot if not careful .
