This is a picture of the inside after about 8 hours of striping and grinding. It looks bad but im happy with how solid the floor is. The PO told me that it is a new floor within the last year. I cut a hole in 3 sections to see inside and there is dry solid stringers in there and the foam is dry. This makes me verry happy!!! There was some carped that was still glued and stapeled down to the floor and it was a real PITA to get it all up. There still is a heck of a lot of grindong to do at this point to get everything flat and get all the carpet glue out. I dont want to put down carpet again im going to paint the floor with non-skid paint so that i can clean it easily after use and carpet will hold water and rot things. Im still a long way from paint at this point i have to glass the whole floor first to keep water out of there.
