Questions & Answers

How long does it take for the substance to penetrate?

My 4Runner's power running boards wouldn't deploy due to rust on the pins...sprayed this on and in minutes they were freed up, followed by some fluid film, and they've been good for months now.

Is this a good substitute for kroil?

Probably not, but considering the price, it's a good deal.

I am completely enamored with this material

5/5

There are no words to describe how I felt. I've tried just about every rust penetrant imaginable, with varying degrees of success. This Mopar rust penetrant, on the other hand, is hands down, without a doubt, the BEST rust penetrant I've ever used to break seized nuts and bolts in any condition or application. To top it off, it works extremely quickly; I wouldn't even consider purchasing a can of PB blaster, liquid wrench, or WD-80. 40, as long as this stuff can be purchased anywhere. If you didn't already know, I'm a huge fan of this stuff.

It performs admirably! It only took a few minutes after a quick spray to loosen it up

5/5

This product was recommended by a Ford technician, and I chuckled as I placed my order; there's a reason we'll both back it up!.

Are You Really Stuck? Get this

5/5

It worked a lot better than the standard liquid wrench/WD40 penetrant. I was blown away by what I saw on a YouTube video. I've used it on a few very old/rusted/stuck exhaust bolts with no problems, and I highly recommend it. Excellent work.

It appears to function properly, but I had a job that was far too demanding for it

4/5

It reminds me of old-school penetrating fluid from back in the day. Because it is flammable, use caution when working with heat. It didn't work on my severely rusted control arm bolt, so it's not some super magical, miracle-working penetrating oil, but it appears to work well and is stronger than the standard stuff.

I've never found anything better

5/5

As a big fan of kroil (which is excellent), I never expected to say I prefer something else. If you soak it in this and let it sit for a while, it will almost certainly come off without difficulty. It's fantastic!.

It's good enough for me if Brian thinks it's good

5/5

I go to FORDTECHMAKULOCO for all of my F150 advice because no one knows Fords better than Brian. He claims that the Mopar rust penetrant is the best, and I agree; it is now my rust penetrant of choice.

This is said to be the best degreaser on the market

5/5

A Ford Tech advised me to do so. He swears by it, so I bought it for him. I have yet to try it.
