my goodness... glue????
interresting- now to see someone willing to experiment with it, do you think it retains some flexability, or is it very brittle??
might be a good sealer for those very porous woods/risers, and then normal finish over the top of it- wonder how it handles uv, and will it degrade/ go yellow over time?
wonder if it would make a good concrete sealer for floors??- if it is durable- those epoxy finishes just wear off!!
