*Metal Prep *
Iím sure this is old news for many of you, but I wanted to share a few thoughts on what I have found that works - FNV. I repair and maintain aircraft engine stands that are outside all the time. Needless to say, they can begin to rust pretty fast. If the rust is major (deep pitting), I use a rotary cup brush on an angle grinder to knock the loose stuff off and then Navel Jelly to kill any left overs. For minor rust and those little nicks that get to rusting, I use a product by Rust-Oleum called Rust Reformer. I get it by the gallon jug, but it also comes in rattle can sizes. It is great for touch-ups and priming cast iron. It is my understanding that it chemically reacts with the metal and turns from creamy liquid to a black tough primer. I have been using it for several years now and I am beginning to see the first areas where I applied it (periodic maintenance cycle) and how well it has held up. Iím impressed. Unfortunately, itís not cheap. But most things that are well made have their price. Being in the aviation industry I am able to apply the EXPENSIVE aircraft polyurethane paint over the Rust Reformer and it holds up very well. The standard Rust-Oleum paints are usually good for 5-6 years outside.
One caveat that I would caution regarding the gallon size container is Ė shake well and pour out just what you need. DO NOT put that back in the jug, or youíll have a nice door stop or chock! Ask me how I know! J It will start a reaction that doesnít stop. Also, be sure to keep the jug sealed up tight. Hereís to a different kind of prepping!
