      I have used this product on our S/Y for 6 years of cruising and it has preformed better than any other. I use it on all my plastics and metals. Rubber however does not like it. It saves me time with no rubbing. I love it.

      I have been using this product for years. First used it on the boat and trailer. Then my travel trailer, now I use it on my motorcycle. You need to stop corrosion, this is the stuff.

        Many uses, but the best one for me is how quickly it will free rusted bolts and nuts. better and faster than other penetrating oils i have used. pleasant smell as well.

        By Vinny

        from Undisclosed

        I live in Kailua Hawai'i and use this product on a new outboard and trailer and I have truly eliminated corrison on the engine and limited rust on the trailer afer two years. This product is second to none. Use it on all tools in garage and fixtures/appliances in the house to stop the corrsion in this tough salt environment. I also put it on parts of my Harley and wipe it off, so there is a vey thin coat, so far no discoloring, corrsion, pitting. Pay the little extra and save TIME in you life.

        By Mike

        from Undisclosed

        I disagree with John's review. I have tried Corrosion X and found it did a very poor job of protecting metal. It also softened the circuit board in my hand-held radio. Finally, it smells bad. Give me Corrosion Block anytime.

        By John

        from Undisclosed

        This Fluid Thin Film technology works very well. My only issue is that this product doesn't work nearly as well as CorrosionX, the other Fluid Thin Film product on the market, and I have a hard time finding CorrosionX here in Denison, TX. Please consider picking up CorrosionX. It's a much better lubricant and penetrant and it was also the top rated protectant in Practical Sailor. Thanks!

        By Climate Boatworks

        from Undisclosed

        Super product! We use this product on electronic boards to prevent corrosion from direct water penetration, or humidity. We have literally submerged electronics treated with Corrosion Block underwater for several days with no negative effect to the circuit boards or components.
