I have a custom project that I have been working on for about two years now, and it has been in bare steel for most of it. I am wondering if there are any tricks to keep the surface rust at bay. I have heard a few rumors about using CLR or some other neutralizing product, but I would prefer to hear from those with experience. In the various stages of mockup and assembly there are areas that are hard to reach with the sanding method. Little help? Thanks in advance peace.
