Is this the scratch? Does it run completely across the bottom?

If it where mine I wouldn’t be too concerned.No its some kind impression in the styrofoam.
It’s three scratches
8”
6”
2”
The longest is unnoticeable with the finger tip. The middle one is BARLEY noticeable and the 2” is noticeable. You can feel all with the tip of your nail.
Are the scratches on the front pane or bottom? You can buff them out similar to a windshield repair. A constant trickle of water across the working area is best.
