It's called Dinitrol AV8 (sorry I spelled it wrong the first time) It is used by all of the major aircraft manufactures as a rust inhibitor. You can spray, brush, or dip parts. Here is a PDF file you can google. There is alot of info on line from car guys that love it. I didn't buy it I "aquired" a small amount from a former employer. It really goes a long way so you don't need much. I had the liquid form so I brushed along a tape line and just let it run. The heavy drips will remain sticky for a LONG time, so wipe them off if you prefer. They also have it in spray cans which would be nice.
