So I've recently taken a more DIY approach to things and decided to change my own brakes / rotors on my car.

Everything was going fine, until I got to the second rotor, and couldn't get the thing to come off. I pounded on it with a mallet for some time (on and off for a good 25-30min), put a whole lot of WD40 on it, but nothing. Didn't even budge. So, I decided to look for a better solution, and found this stuff recommended on various auto forums. Most everything I found said that if this couldn't take it off, the last resort was going to be a cutting torch. So, I bought a can.

Took it home, sprayed it in between the rotor and into the bolts and was surprised to see that it did actually stick pretty close and didn't drip as much as the WD40. The stream is very precise and lets you get into small spots without a straw. I let it sit for a couple minutes, and came back with a dead blow hammer, and a few hits later was on my way again.

I wish I had this stuff to begin with. It would have saved me a lot of time and frustration. It's not fancy, and looks like a bottle of snake oil with all the promises on the packaging, but it comes through and does what it promises.

If you have something rusted together and stuck, this will save you a LOT of time over other options. For the price (< $5), it's definitely worth the time.

I've used Kroil, WD-40, Tri-Flow, Naval Jelly and other penetrating solvents with limited success. PB Blaster is the first product to deliver what I expect- spray it on, wait a couple minutes, problem solved.
Let me tell you about my first experience with this product- I first noticed it because it looked a little 'retro' on the shelf, especially next to the bold colors of the other brands in the section. I bought a can, took it home and put it to work right away on a frozen car door- a 72 Mercedes 220 where the door was absolutely frozen shut. No amount of any other penetrating oil even made the door wiggle. I sprayed this stuff in the crack toward the latch, waited a minute and the door opened like it was brand new- magic. I've used it on hinges, manifold bolts, brakes, pretty much anything that is supposed to move but doesn't move right. It's like spraying magic in a can.
Several reviewers have mentioned the smell. My wife hates the smell, but I love it because it's the smell of success. I wouldn't spray alot of this stuff in a small enclosed area- and warn the wife before spraying in the house at all.
In short, I would unreservedly recommend this product to anyone needing to un-stick a part.

MY EXPERIENCE: OK lets start off with the toxicity claims. First of all, I do believe this product to be toxic. For one thing, I don't like the smell of it! Secondly, without a doubt, if you sniff too much of this stuff, your going to get light headed, or at least feel like your mellow yellow on liquid wrench, macromaying your head into the car bumper. The thing I don't like about this stuff, is that it does not come with a straw. Oh sure it claims to have pin point accuracy, but that is a joke. If you want to focus the blast right where you need it, you need a straw, and they don't even provide that for you!

As far as its claims to be magnetic, surprisingly it is! I don't know what is in this stuff, but you could put a metal object on a up-hill, and spray PB just bellow it. And the PB will slowly climb up to it like a worm going after its food. This works really well, cause I can spray this stuff into small crevices on an engine, or door hinges for example, and the product just works itself up in there.

As far as a lubricant, it works really well. It does actually do what it claims, you spray it on, it stays there, works great. Now, as far as penetrating ability is concerned, this stuff is amazing. I really like Marvel Mystery Oil as a penetrator, but I have to admit, this PB is good stuff, works great. They sure have a lot of fancy wording on the can, obviously its all meant to attract attention to the product on the shelves, as its always the one that stands out from all the others.

CONCLUSION: As a lubricator, it keeps parts moving smoothly. As a penetrator, it freeze up rusted parts. As a magnetic attractor, allows the product to get deep into crevices to better lubricate and penetrate whatever you have the product on.

I was working on a 12 year old Ford truck with a broken and rusted exhaust manifold.

I had to get a total of 12 bolts off in order to take off the manifold from the flange and engine block. The bolts wouldn't budge with anything I did.

Originally, I tried a combination of WD-40 and Lithium Grease, but no luck. I then became desperate and decided to use my friend's recommendation. I sprayed PB Blaster on the bolts, threads, and any where the PB Blaster can reach in the manifold bolt area, routinely for 2-3 days. You actually see the penetrant seep into the bolt and it looks like it disappears on you.

I got all the bolts off with relative ease and I am now a lifetime user of this product. Not sure what's in it, but it really instills a whole bunch of confidence when you work on what you thinks as impossible to remove.

Hope this review helps.
