Bleed Thru

[Chariots of Fire]

I've had bleed through issues in the past.  IMHO it has to do with the plastic and not the paint.  I have primed red plastic with Duplicolor gray primer on some red plastic with no issue.  Next time around on an other kit of the same model and the red bleeds through.  Same with yellow plastic when trying to apply white color coats.  Really a pain when it happens.  I found the issue to be really bad with the Monogram 1/32 scale CF Mack kits.  I put to cabs together using the same color plastic and on one half the yellow bled through.  On the other half it did not.  Weird!  Took using 3 different cabs until I found two that I could join that did not have the bleed through problem.  Here's the final result of the join after priming.
