just apply a little release agent to the areas you have x-d out. The epoxy will stay put pretty much as long as you dont overdo it. The little bit that rolls over the edges can easily be chipped of with a small chisel or screwdriver and a light tap or two. I drilled a few small holes in each of the piers for a little extra grip and removed maybe a 16th or so all around the pillers so the epxy would have a place to go and to ensure metal to metal contact at the pillars. Did a couple of the tupperware stocks with good results.
