Thanks for the info b-man. I cleaned up my floor boards today and they were not as bad as I thought they would be. Biggest area of damage is about the size of a 50 cent piece maybe smaller. I will use your fiberglass method for the repairs. It seems to do the job really well. Just wish I could find POR-15 products locally. I hit up all the local hardware stores and autoparts stores today and no luck. Nobody carries POR-15 locally.

I discovered a rats nest of wiring. Going to redo everything.

Pretty clean in my opinion...
