It will rust. Not quickly unless you are by the coast. Problem is, it has a coating that is difficult to remove. Sandblasting is what I use if I have to use it. You cannot galvanize it unless you remove the coating down to bare metal. Not sure if it will take paint. Probably if you degrease it pretty well.

Has anybody used black pipe as a mast before? I'm concerned it will rust out relatively quickly -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
