That's very true Tom. As a PM/Estimator I've (fortunately) not seen a failure that was not caused by multiple bad details or conditions.
The crystaline material wont stop water penetrating but ought to slow it down considerably. A masonry or metal cap over both chimneys would help as would a desner finish materail over the CMU's. I believe that WP material will also allow for a veneer application at a later date w/o becomming a bond breaker.
Might not look real good in the mean time though.
