Hi-looks like they didn’t do a great job sealing the bolts for the swim ladder on my swim platform and some water got in there. I had a 4x20” stainless backing plate fabricated for strength, but was wondering if anyone had any recommendations about filling any potentially rotten wood inside the platform around the ladder bolts without taking it off and redoing the whole thing. The rest of the platform sounds solid. Any suggestions are greatly appreciated. Thank you in advance
