- 16-PB-12PK - Penetrating Catalyst - 11-Ounces - Case of 12

This stuff works! It was able to loosen a rusted axle nut on my bike when nothing else worked. Definitely worth the purchase.

I grabbed this Blaster spray for my old Honda and the junky carts at work. Night shifts in the hospital lot mean I am always dealing with rusty stuff in the dark. I soaked a stubborn bolt on my car exhaust with it and could finally break it loose without swearing at 3 a.m. That alone made me pretty glad I bought it 😅. I do wish the smell was less strong though. I have to leave the garage open for a while or it lingers on my scrubs. The nozzle works well, but it can drip a bit if I spray too long. Still, it does the job when things are stuck.

Great penetrating oil, especially for working on brake calipers and for penetrating nuts and bolts that are rusted in place. Does a much better job than WD 40 which is not a penetrating oil. Good price for 2.

This is great stuff. Many mechanics that I know use it as a proven loosener of stuck bolts. Sprays out foamy and clings well. Good price too!

It works. Might not be the best. I have used for years.

Works great on sticky parts on my sewing machine. A great buy I use it for other things around the house also

Ive been using this lubricant for many years. It does the job to loosten rusted nuts and bolts

Works great. On occasionally it may take a couple minutes to penatrate the object to loosen it, but 98%.of the time the object will open.

Product may be good , but it is seriously overpriced on Amazon. Less than $10 at princess auto. Amazon won’t let me return it , regulated product?
