    Epoxy over waterbase ??

    I was wondering if I can finish coat a plane with epoxy that has had the glass cloth originally put down with water base poly urethane ? I'd let the waterbase "gas out" for a couple of weeks but then would like to finish it with either Z poxy or the West System. Any info would be appreciated.
    thanks,
    paul

    RE: Epoxy over waterbase ??

    Just curious why you'd want to put another coat of resin...
    If the glass has adhered properly, why not go straight to primer and start filling the weave that way... usually lighter than another coat of resin...

    Thanks mark for your reply.
    That's a good point as I have, in the past gone right to primer mixed with micro balloons and got a pretty good finish. I was just just exploring the idea of using the epoxy over the waterbase to get that hard, even finish. Additionally , the cloth is a bit easier to put down with waterbase.

    RE: Epoxy over waterbase ??

    The support of the epoxy would be limited by the flex in the underlying polyurethane. If you wanted a hard epoxy finish you really should have started with it and continued. Now you are risking bond failure issues due to flexing and possible incompatibilities and possible cracking of the epoxy if the polyurethane and glass substrate is too flexible to support the epoxy well.

    Not to mention that you'd be adding a heavy material on over an already heavy base prep.

    So I'd say just go with the primer and final finish instead of epoxy.
    Witty saying to be plagarized shortly.....
