I could not find this topic discussed

Does anyone have any experience with refinishing the existing plywood floor in a 53 panel ? Do and don'ts ?

I know every trucks condition would be different, in my case the wood is tight with the original top ply intact with the exception of a wear spot about a foot square where the top 3 or 4 plys have been worn through. [bummer ]

What would the stain color be if any ? It's a 3800 if that matters

Thanks
