I forgot the name of the stuff right now, comes in a spray can.

It comes close to freezing the item and shoots a penetrating oil at the same time. You can buy it at Autozone, Advance, O'Reily's, et cet.

I have used it now 3 times and it has really worked 3 times. It comes in a black can, but its name escapes me right now.

I will look on the bench tonight for the product info.
