    I have a gallon of NCP271 primer that I used on a project several years ago and it has been sitting on the shelf sealed up since then.
    I opened it up and it has obviously separated from sitting. The solids are at the bottom and the, what ever it is liquid, is at the top.
    The solids are semi hard but you can dig it apart with a stir stick.

    The question is is it still good. Can I take it back to the supply house and have them shake the hell out of it to remix it?

    I was going to use this as my final primer before BC/CC.
    Thanks

    Any time I have to question if a product is good or not, it goes in the trash. Its not worth it to risk paint failure and having to redo something. But you can usually look on the tech sheets and it will tell you the shelf life of any product. I would just get a quart of your favorite primer and use it instead.

    I agree. Not worth the hassle. You will have to buy the activator anyway (as most have a short shelf life), so why not spend the little extra on the primer as well just to be safe.
