come to think of it, the fronts are dark blue.

Coffeechick,

Like most folks, it looks like you've been drummed into the ranks ragarding PB Blaster. To me it's useless.

A product called Kroil, made by Kano Industries, is the best penetrating oil you can use. The drawback is it's a mail order product only.

I did a little test using PB Puke and Liquid Wrench Penetrating Oil.

Th Liquid Wrench spray can says it dissolves rust. Let's see....

I took two small containers, one with PB added and one with Liquid Wrench added to them. Put two identical rusty bolts in the containers and let them sit for two full days.

The container with the Liquid Wrench actually shows rust deposits on the bottom of the container and the oil itself turned rust colored. The continer with PB had no change at all.

What does this prove? Not much, other than it looks like Liquid Wrench does what it says it will, and that PB Puke remains low on my penetrating oil list.

I'm in the process of douching down several bolts in my Heep using Liquid Wrench to see how it works (I ran out of Kroil).

Besides, LW smells better than PB. My wife likes it when I come to the diner table smelling like LW.

Lowes sells LW.

I actually ended up getting a can of Liquid Wrench a few days ago, and it's what I was using the last couple of sprays.

It does smell better, and it seems to work better.

See....

PB was my go to for several years but I'm a kroil convert!

I've read a lot about Kroil. And various home remedies.

Right now I have to use what I can get, though.
