MEM,
the soap foam seems to be working well. I used it to fill missing wood in a rotted piece of framing in a boat and the foam is harder than the remining wood.
the rotted section went through the piece, spliting it in two. the foam is holding those pieces very well.
to finish the repair I'm going to cover it with fiberglass. the soap foam is harder than the 2 part foam I used elswhere so it should perform better too.
It would be nice if Gorilla could provide a 2nd component that would produce consistent results. Using dish soap, I get consistent results only so long as I use the same brand. Someone else using a different brand may get results much different from mine.
