I have been applying epoxy to all of my plywood. It has been going ok at best, hopefully it is at least waterproof. But in prepping the back side of the ply wood I first sanded all the drips that hardened from the initial three coats of epoxy as well as a quick roughing of the edges to build them up more. Now when I started wiping the ply wood with a damp sponge some of the plywood now has an odd pink hue. Is this a cause for concern? Something I need to sand off? I am not worried about optics just waterproof as it will be covered in carpet or vinyl depending on the piece. Oh and this is not occuring on most pieces and they have dried for at least 5 days.
