    Hi all
    Be starting a car bodywork soon.i used to start on
    bare metal zinc rich primer-high build 2k then paint.
    Then zinc rich primer-epoxy-high build 2k then paint.
    My questions are is there any one coat epoxy primer with zinc ?
    Do I need zinc at all?
    What are your opinions

    Edit : What they said ^^^^^^^^^^^^^
    I would say no you do not need the zinc primer, and go further to say, any coating under the epoxy will reduce the epoxy's adhesion to the metal. All to need is clean rust free base to spray or brush on the epoxy, then go to 2K high build etc.
