I am talking an order of magnitude difference. We aren't talking
a 20-50% improvement in efficiency, but in this particular experiment
nearly 2000%.

The active ingredient in WD appears to be Mineral Spirits available in
1 gallon jugs for less than 10 bucks from the big box stores.

So less than 8c/oz vs 30c/oz. for WD.

I would be very interested in your test results using Mineral Spirits
as a cutting fluid for aluminum.


Kerosene will work equally well.
