Sorry it took so long to get back …..
The foam came back to where I just needed to peel the canvas back and used a little bit of filler. (1/16 in )
I glued the canvas back down, and put a coat of paint over the repair.
It's about a 6 foot repair, you can't really see it from about 6 feet away.
Up close you can still see where it happened, but I haven't tried yet to make it match the rest.
