[Milsurplus] Painting Aluminum - BC-348 in particular

[WA5CAB at cs.com]

That's probably Zinc Chromate primer.  I don't think you can buy it anymore 
thanks to the obamonkeys running EPA.

However, my experience with painting BC-611 and other parts the last few 
years is that Rustoleum red oxide primer works well.  And you don't often have 
the nozzle clog problem common to zinc chromate.  Bead blast or sand the 
surface immediately before priming.  I have no longevity figures, though.

On the subject specifically of black wrinkle finish paint, I recent got a 
testimonial from a customer who had painted the cabinet of an ARB.  He found 
a paint new to him (and to me) at Auto Zone and another auto parts place 
that didn't register (Advance Auto PArts) as there aren't any in Houston.  Made 
by VHT  Products Co. in Cleveland, P/N SP-201.  He said that it worked 
great.  The downside was it required oven time.  However, I would suspect that 
about 14:00 outdoors on a summer afternoon in either Houston or Austin might 
be a reasonable substitute.  I haven't tried it yet myself but it reportedly 
yields a fine wrinkle, not the coarse stuff from what Pep Boys and some 
others sell.
