Alclad II grey and white micro filler and primers have very fine pigment and dry to smooth finishes. I have used them as a primer for resin, white metal, and plastic kits without any issues. I use acrylic paints and clears almost exclusively and have not experienced any problems applying them over the Alclad. It is airbrush ready out of the bottle, doesn't require any thinning, and cleans up with lacquer thinner. The Tamiya primers work well also, but the bottled variety require thinning (I haven't tried the rattle cans). I build mainly in the smaller scales and automotive and hardware/big box store primers are non starters for me too (for the same reasons you stated).. These models were primed with Alclad and painted with Tamiya and Vallejo acrylics.
