Works well quickly and cheaply
This stuff is really really good you can spray it on metal parts under the underside of your car and it will protect them for a long period of time if penetrates the metal surface it really bonds to it it sticks it's very smelly but it works pretty good. If you have a bunch of rusted bolts that won't come off this really really will help them it kind of breaks down that rubble that rust in a lubricates them in such a way it's hard to describe. Worth the money.

Good Stuff
I tried soaking in both wd40 & 3&1 oil and could not get a broken splitter off my outdoor hose spigot for over a year through a sometimes single digit winter so I was thrilled when this worked. I only left it on 10 minutes & I also used a special wrench specific for unscrewing a hose but it was worth it not having to pay a plumber :)

Great!!
If you do any kind of automotive or DIY work, you already know PB Blaster is the gold standard. I had a couple of suspension bolts that were completely seized and rusted solidโI soaked them for about 20 minutes with this stuff, and they broke loose without me having to snap a breaker bar. It really does "blast" through the corrosion in a way regular WD-40 just can't. Itโs got that classic strong smell, but Iโll take the smell over a snapped bolt any day.

Universalwaffe gegen Rost
Nicht "auf Rost", sondern "gegen Rost". Rost stoppt das Mittel nicht sicher, da wรผrde ich Owatrol vorziehen. Was aber faszinierend ist: Blanke Metallteile wie z.B. Schrauben im Motorraum, am Fahrwerk eines Autos bleiben fรผr Monate rostfrei. Vertrรคgt sich mit Gummi! Einsatz deshalb: Bei den Oldtimern regelmรครig die offenen Schrauben und Leitungen aus Zink versorgen. Hauchdรผnner Auftrag reicht vรถllig. Kurzer Sprรผhstoร entweder direkt drauf oder auf einen Lappen und Bauteil abreiben. Schรผtzt fรผr die ganze Saison im Motorraum und fรผr die halbe unterm Auto. Alle Verbindung bleiben blank und lassen sich leicht lรถsen. Halter des Auspuffs, Clipse der Leitungen, Blechklammern der Zierteile uswusw. Einfach kurz ansprรผhen und Ruhe ist. Sehr wenig hilft sehr viel. Bei entwรคsserungslรถchern gebe ich gelegentlich einen Spรผhstoร hinein, damit sich eine nicht bewitterte Schutzschicht bildet. Blechรผberlappungen (Kotflรผgelkanten im Motorraum, Nummernschildaussparungen usw.) werden einmal jรคhrlich konserviert und sehen tadellos aus. Da ein etwas lรคngeres feines Sprรผhrohr fehlt und ein Sprรผhstoร oft schon zu viel ist, gibt's nur vier Sterne. Ich habe ein feines Rรถhrchen von Ballistol in den Spรผhkopf gesteckt, das hilft beim Zielen auf versteckte Schellenschrauben. Riecht etwa streng petrochemisch, verfliegt aber schnell.

Questo funziona bene
Meglio di tanti altri sbloccanti, forse il migliore tra tutti quelli che ho provato, e non sono stati pochi. Ovviamente bisogna dargli il tempo di agire e non pretendere l'impossibile. Consigliato!

An important tool
Effective combined with hot-cold cycles and appropriate mild leverage. Take your time.
