Stu,
I own and use Kroil often (on rusted bolts and parts) and I do like the way it works. My problem with it is the smell it exudes. Question: Does the Microil have the same smell as Kroil and is the Microil just a smaller can of the Kroil or a different product?

I use the Aero-Kroil which to the best of my knowledge is just Kroil in a spray can with propellant.

Thanks in advance!
