    Default Rust is a Bust!!!

    If your bolts and nuts are as rusted as mine were, you might want to replace before they snap on you(like me).....

    Thanks for the heads up. That could get ugly if they let loose on the highway.

    should I try sanding off the surface rust first and then hit EVERYTHING with the rubber coating?

    Im not too experienced with paint or prevention of rust but if you are going to sand it I would than use a sealer like a primer, then the rubber sealer.. I could check tomorrow though. I will check tomorrow..Good question.....

    There is a liquid rust neatralizing solution which may be a good idea oto apply after wire wheeling/ sanding and before the primer and rubber spray. I don't imagine paint or rubber would do much on exhaust pipes though,probably be pleanty foul smelling till it all burns off...

    There are a few different brands and types of rust inerting/converting products out there. Currently I'm doing the same thing with my Chicago car. I'm using the paint on type with an acid brush. Basically, degrease the area, sand as much of the rust off as possible, and paint on. It's easy to spot the rust because it will turn black almost immediately. I've got the entire rear beam out of the car except the gas tank, and am cleaning up areas of rust along with replacing all my hardware. I posted a progress report the other day if interested (540 progress). Definitely look around the diff. carrier bolted to the body, and underneath if possible - around any of the welded on brackets too. I am following up the conversion with the Dupli color spray undercoating which is the non-gooey type, leaving a nice semi-gloss hard finish. Great stuff so far.
    May the Schwarz be with you...
