re: WD40 and paste wax

Potz, I used Johnson's as a final coat for my finishes for 30 years, but my can got to where it came out blotchy.  It had been regenerated with mineral spitits many times.

I switched to Varathane's Finishing Wax and it beats the Johnsons by a large margin.

Have not used it of steel, but the look and feel on wood is great.
