Rated 5 out of 5 by from The most important tool you will ever own. Currently restoring a 1951 Ford 8N tractor and so thankful that I have PB B'laster. The time and grief you will save yourself is priceless. If anyone is doing a restoration project, the first tool I would recommend they have is PB B'laster. So grateful my dad taught me well while teaching me mechanics as a kid.

Rated 5 out of 5 by from B'laster Got Us To Safety! Hello, my wife & I have an interstate hotshot transport business. During some very bad winter storms last month in Utah, my wife noticed a squealing sound from the front of our '97 F350 diesel pickup pulling our 32' freight trailer. We pulled into a rest area thinking a wheel bearing had gone bad & upon opening the hood, we found that our fan belt-tensioner pulley had locked up with our fan belt squealing across it. We were still 30 miles from any civilization in icey, bad weather & had to think quickly. I grabbed the pulley with vise grips, broke loose the pulley and sprayed B'laster into the bearing of the pulley while slowly turning it. Not only did PB B'laster get the pulley spinning again, but kept it working to get us into the next town for repairs. The mechanic was amazed that the pulley got us 30 miles into town & we owe our safe return to your product. Please let your people there know how thankful my wife & I are for the quality of B'laster. Sincerely, Gary & Tammy, Riverview, FL.

Rated 1 out of 5 by from The spray can is terrible. If you use it every day you'll love it. The product is great but if the can sits for more than a few weeks the sprayer is junk. Push the nozzle down and all you get is B'laster-scented air freshener, the penetrating oil in the can is useless because there's no pressure left. I would buy it in liquid form and just pour or dunk as needed but I can't recommend the spray can variety. It's literally a waste of money. The last three I bought were nearly full when I threw them in the trash because they didn't work.

Rated 2 out of 5 by from It works but only once I have now purchased 3 cans and all three I used one time and left for a few months only to need them again and no pressure. At the price, I will only buy when wd40 doesn’t do the job. I am disappointed that they can’t invest better in the cans and pressurizing, the actual product is bar none amazing on 20 year old Jeep bolts.

Rated 5 out of 5 by from PB Blaster works everytime Working on a car wash system and had to remove a bunch of rusted bolts and as usual the hex head is no longer that shape anymore so I drenched them in PB Blaster and gripped the vise grips on it and said a prayer........boom they unscrewed like they weren't even tight.

Rated 2 out of 5 by from Loses pressure, doesn't spray This product is amazing, we use it often. Unfortunately we have noticed most of our cans clogging and not spraying after being used one time, they are usually 3/4 of the way full and we can no longer use.

Rated 4 out of 5 by from Good product but I purchased 6 cans part no 16PB and every can ran out of propellant long before product was used. I punctured the cans and recovered 13 ounces of product. All cans were at room temp. SUCKS
