What would be a good paint to simulate galvanized corrugated sheet Iron? I am using Campbell corrugated aluminum which I have etched with acid to make the paint stick. Floqul’s “Old Silver” is out because I have used that on some parts and want to set the siding apart. Any thoughts?

Hmm, I think everyone has their own preference for representing galvanized.
For new galvanized metal, I find the standard Testors Silver (not Chrome Silver) + Dullcoat/Semigloss works very well (at least to me).
For galvanized metal that’s been out for awhile, I had some success with a silver basecoat, then light passes w/ light grey primer (I was using a spray can, so this was a bit tricky - airbrush should be easier) - then a light dull-coat pass, as you still want a bit of shineyness to the model - think sign posts or parking meters or electrical conduits. If you want a completely weathered sheet, maybe go w/ the silver-grey primer-dark wash-lots of flat/dullcoat, with touches of rust (red/brown/orange chalk) at the edges.
Are the sheets still shiny after the acid etching? If so, you could try spraying them with a fairly dark grey (maybe Floquil’s Reefer Grey) in a “spatter” pattern - make a quick pass (or two) with your airbrush, from a greater distance than normal. If the sheets are no longer shiny (or maybe even if they are), you might also try some Old Silver, using a similar technique. Most galvanised steel doesn’t stay shiny very long, so it will also depend on the age of the building which you’re modelling.

Campbell’s kit instructions suggest for not brand new siding to use Floquil SP Lettering Gray, which to me looks just like any galvinized metal that has sat outside for any length of time.

If you have an extra sheet or possibly try on the back of one of them to just spray it with dull coat after you have acid washed them. maybe some gray or rust wash before you dull them out?
