Firstly, let me state that I don't work for, or sell, or receive any compensation from any lubrication company. Reading through the posts on this site I see people recommend the use of PB Blaster frequently. I have used it and found it very effective almost all the time. Some people mention effective use of something called Kroil as well. I have never seen Kroil product in CT before. I notice that Liquid Wrench and WD40 get very little love here at all- they are practically a dirty word with some posters! I would like your opinions on a product that I have recently discovered(3 years ago) I tend to grab it more than the Blaster and I find it just as effective. Has anyone used Gibbs penatrating oil? I was turned onto it by a friend who is an avid boater. He swears by the stuff and uses it to bust up frozen bolts for marine applications. Anyway, he gave me the last little bit in a can one day and I was so impressed I ordered 2 more cans on eBay a few weeks later. Fast forward a few years and I need to reorder again. Before I do, tell me what you think. Please be honest. Oh, and the reason I like if better than Blaster is the smell. PB smells revolting to me and it is strong smelling too. I used it in the house once and boy was that a mistake! Has anyone used this Gibbs stuff?
