Quoted from twenty84:
This damage was caused by the guide scraping the play field. Seems like if you don't have any damage you are trying to cover a simple washer would be enough to lift the guide off the play field.
Yeah the washer fix is what most people are doing, unfortunately I was unlucky and have some pretty bad damage underneath that guide. While I get the complaints about it being a little long (again, it's his first draft of it), I'm incredibly happy with it, as it completely covers the damage, and now I know it won't get worse.
The final iteration will be shorter, for the time being this was a WIP based off his LOTR protector for a similar issue.
