    I suppose I should have asked this question before I painted my firewall but if anybody has experience with it I'd appreciate the heads up.

    I don't think you'll have to worry about it on your firewall. I can only imagine its at least more heat resistant than regular paint, and that does fine on firewalls and engines.

    go to

    see all the type of paint they have.
    Regular por 15 on a fire wall will work just fine.

  5. I stripped my outdoor barbeque grill ( big old Ducane) last July and repainted it with black POR 15.
    Looked nice for about 3 weeks then it faded to a chalky looking
    greyish - black.
    Looks awful now but it's not peeling!

    He is right, POR 15 does not like light, don't try to paint over it what ever you put on it will not stick. They have a product called tie coat(?) that you cann apply and the paint over that. POR 15 will take what ever you throw at it except for an open flame (even that takes awhile)

    The temp will not matter for your car I am guessing about 400 is the max it can go. Also i think its an epoxy and those normally do not take UV rays and tent to fade and chalk. Top coat for the best look.

    Isn't there a POR-20 for high temp use?
