So I had some MM full length, weld in, sub-frame connecters installed. The guy installing them said I need to coat them in a rust inhibitor (sp??) because they will rust without it. Any ideas on what I can use?

Thanks,
Matthew

 

My brother had subframe connectors that were powder coated and we just painted over the welds so they wouldn't rust (they had to grind off some of the powder coat to weld).
