I'm making a couple of gate frames from 1X3 11ga , and it's developed a but
of light surface rust - you can wipe it mostly off with your bare hand . Do
I need to wipe it down with maybe some weak acid solution , or will a wipe
with rag/degreaser lacquer thinner most likely and use of an etching
primer do ? I'll be shooting the primer and maybe brushing 2 coats of
industrial enamel .
No matter what the finish , it's gonna be a problem getting it to dry
right now ...

Jasco used to have a Prep and Prime solution that was mainly
phosphoric acid, removed and/or converted the rust. Used it a lot on
stripped autobody parts before priming, those started rusting
immediately after removing the paint.. Basically a wipe-on/spray-on
type of thing. If it's cold, it'll take a LOT longer to react to
rust, best to find a nice warm garage or basement to do it in.

I can't remember the name but you can get that stuff from Home Depot.
Look carefully at what you're buying: you want to get the stuff whose
directions say to squirt it on then scrub with steel wool.

(Damn but this brings back memories. One of my jobs at my dad's shop was
to take the freshly-straightened sheet metal and put the first coat of
primer on it, after scrubbing it down with that stuff. It has a
distinctive smell, not unpleasant except that it smells like work).
