Has anybody tried one of these or something similar? My steel post are all rusty (as I am a little OCD) and I would like to have something I could spray that is cordless and works good without the hassle of dragging a generator and/or electric/gas air compressor around spray painting. When the steel post rust they rust the cross wire even though it is galvanize and shortens the life.
