OK, here's the update.
Mainly my fault in not researching it further. Line X claims no responsibility but has offered to redo it completely only charging for the material once I remove the Line X and the Diamond Shield. I'm comfortable with that although it is going to be a huge undertaking. It won't matter if the paint is damaged in the process as it will be covered with the new Line X.
Some had said that they painted directly over the Diamond Shield but in talking with DS they will not recommend that at all. Says it definitely needs to be removed.
My final comment is that you should never try to cover up the Diamond Shield (or whatever the coating is). It HAS to be removed.
I appreciate the posts that offered opinions that were constructive
in nature as that is what this forum is for. The non-constructive ones obviously have nothing better to do with their time. Kinda feel sorry for them.
We are heading out with the mh as it is and plan on enjoying the fall weather and colors. I'll address the removal issues when we return.
Happy Travels to all
