Hairline crack in dometic toilet front rim

[dcavaiani]

Any remedial steps advised? Any others whom have experienced this?

I know of no successful repair of cracked porcelain other than super gluing a handle back on a coffee cup.

Replacement is the only option I can forsee.

If it is not that old you might send that photo to the manufacturer, they might warranty it for you. As a retired plumber, I have seen lots of cracked toilets. I replaced them all.
