Rattle can paints

Never mind peeps. A little research says I would just be well of to buy a panache H and use one of several of the air compressors I already own or to buy the sweet paasche dual piston compressor with tank to put under my desk. 

I have used Duplicolor brand of auto paints a lot.  However it may not work with all primers.  Test on scrap or a plastic spoon first.  It works best wit auto body primers.

I used to use Rustoleum spray cans but now they will not work over Rustolum primer! Go figure.

I used to use Rustoleum primer, and also Walmart's house brand of automotive primer.  They both covered well, though they were a little grainier than primers made specifically for scale modeling (like Tamiya's Fine Surface Primer).  But that wasn't a big problem, because you can easily give the surface a swipe with something like rough paper towel or coffee filters, or green scouring pads to knock it back if necessary.

The problem I had was that both brands changed the nozzle cap on their cans, and both the nozzle and the neck of the can where the nozzle inserts would clog.  I could clear the nozzle easily enough by a soak in SuperClean and some fine brushes and needles.  But I couldn't clear the neck of the can.  I wound up with half a can of paint that I couldn't get out of the can.  And it wasn't worth it to me to deal with that, so I stopped using those products.
