Hey what a good example of the pre repair , if you had not put that foam into your hull pre collision your damage would have been a lot worse. I am considering foaming the void in my sponsons as well in prep for the someday my boat gets hit or I hit something.

What brand of foam did you use ?
I have can of Minimaly expanding foam,and another of the Triple exbanding foam, as you pointed out this is THIN glass so I don't want to blow out the seams.

Thanks D
