I knew I had a couple of soft spots on the floor area but I’m still fishing at this time and I really wasn’t ready to replace it yet, but what started as cleaning turned into demolition. It turns out the whole floor area is bad, I was literally walking on the foam and braces. I’ve done some reading and going to try to leave a nice edge all The was around and deck on top of that. I’ll post pics if I can and try not to ask stupid questions as I go....I’ve never attempted fiberglass so it should be interesting.
