content: Castle Endura is the best automotive lubricant ever created by mankind. I am not kidding. It sprays on as a liquid and and solidifies into something the consistency chicken grease after 15 minutes or so. It wicks around surfaces to places that are had to reach, then solidifies stays in place and does a great job lubricating.In addition to basic moving parts lubrication, it is really good at blocking or preventing rust. If you have a pickup and find the bottom seam on the tailgate rusting, spray Endura on, let it solidify, and then let road dirt accumulate in it. The result is a watertight seal the completely stops rust. It is also really good in doors and tailgates, where you can spray it in drop holes and it coats the inside, slowing rust.Highly recommended!
