John I was thinking about your cab and that front corner that was bondo'd. If you cut that whole corner off and add another piece with either a couple dowels or a biscuit to secure it, it would work nicely and would be 99% wood. Just thinking out loud.
Yeah, I think that is my plan. The wood is split down the middle at the t-molding groove. If you are looking at it straight on, the left side is the original wood and the right side is all bondo right now. I was gonna try and smooth it out and glue/dowel a new piece in there and then cut a new t-molding groove.
