Is the cure time on enamels really that outrageous?  I'm going to be working with enamels primarily, although the bodies of the cars I'm doing will be done in lacquers - which is obviously going to be the most visible part of the model and the thing I am going to be concentrating on the most to get as absolutely close to perfect as I can.  And as much as I would love to use a Tamiya primer, right now those things are obviously next to impossible to find readily available.  So would I be okay with a Testor's enamel primer for now?  What is the average cure time on the enamel paints?  And how long after priming (with an enamel primer) should I wait to start painting?
