The shingles that are rough must have what is called flat grained wood and over time it will raise up and will cause the paint to crack and peel. This is the only thing that makes sense to me as it is random and I doubt just these shingles are installed wrong.
I would just sand those shingles smooth with and electric sander and recoat with the Cabot product. |
