Pulled off a clean edge on a tricky staircase form
The forms were old and warped, so I spent extra time sealing them with foam backer rod. When we stripped it, the lines were sharp with no blowouts. Really proud of that attention to detail paying off.
I read somewhere that foam backer rod is mainly for concrete gaps before caulking. That was a smart move from @tylerburns to use it on a door jamb instead. It makes total sense for filling uneven spots behind trim on warped wood.
