First: my shop is 100% Grizzly. Planer, Jointer, lathe, drill press, bandsaw, and Tablesaw. I received shipment of all these tools at same time and after I cleaned all the shipping grease off, I treated them with Slip-It. I treat all my tools once per month and twice per month when it is more humid out.
Works as advertised. I have a delta Mortiser that I inherited from my dad. I store this in a storage building while I built my shop. A lot of surface rust formed while in storage. Upon getting it out, it was hard to move. A little Slip-It and it moves smoothly. Great product and I am about to order more.
