Frank, here is an idea to think over:
My friend Rob(SNRGrailroad) was over learning about using routers and came up with this concept. He routed out a recess for a badge and a patch from the fire department he retired from. He applied plastic casting compound over these items in the cavity to seal them in and protect them. Rob spent the time sanding through a set of MicroMesh sanding sponges until the plastic had a clear surface. I think the result was pretty good.
I was wondering about using this method to seal and protect your picnic table carving? This would still show the beauty of your sign and have a level surface that items would not catch on or tip into. What do you think?
