OK, so after a little searching I found a post by Nick Schade who said to stain the panels seperate. So I have taken the deck apart the the appropriate panels are drying.
As I was doing this it occured to be that I am going to end up with a line of light coloured filler in the seam that connects the front half of the deck to the back half (WD12). So, my question is had anyone ever tried to stain wood flour filler? I realize this will not work once it is cured, am thinking that either I stain the wood flour before mixing with the epoxy or add a couple drops of dye to the mix before applying. It is aniline water based stain that I have in powder format. I will do some experiments and let you all know how it works.
