I bought this product as soon as it came out to give it a try and compare it with WD-40. What I noticed about this product was that it lasted a lot longer that WD-40. I applied it on my boat trailer that I put in saltwater twice a week or so and I noticed that it wasn't rusting where previous trailers would rust, and in the areas that had rust, it slowly started taking it away. The process of reapplying is very easy and at first, there's a weird smell but it goes away almost immediately. I no longer use WD-40 and instead use this product. I would heavily recommend this to any type of mechanic and even house hold user that wants to take care of any bit of rust.
Its way better than WD-40 or anything else I have used and lasts a long time even through power washer. Its all I ever use and it doesn't evaporate.
