From the Amazon description of the spray in your post:
DO NOT use this product in an attempt to repair or resurface any type of cooking equipment
Use on cutting surfaces such as saw blades, drill bits or on flat surfaces such as table saws. Works to lubricate tight tolerance gears or flat sliding surfaces such as treadmills.
So no, this is NOT for food surfaces–it’s meant to be used like WD-40.
Your assumption about the veracity of the “Best Nonstick Pans” site is correct.
