Does a good crown coat keep water from seeping in?

    Hello
    This is a single flue 8”x8” block chimney with brick only on the outside top roof portion. It has a clay flue liner and a Selkerk Masonry Conversion Kit with a Stainless Steel liner going down to a P61 in the basement. The new stainless steel Buderus boiler flue is right behind it. It has a concrete crown with a few of cracks. Little if any water gets in but coming into winter sealing it up maybe a good idea?
    Has anyone else done this?

    No mason/fire srack expert, but it looks like you dealt with it in a positive manner.

    Only thing would be what was used for the new see-ment. I have no idea what to use/avoid.

    Looking good!
