So, I was not able to find Seal Coat anywhere in the next big town over. The tru-value here cannot order it, neither can the lumber store, so based on my previous snafu Poly is out. I know it will absorb blotchy.. Is there anything I can put over Shellac as a protective coat? Will an automotive clearcoat adhere to the shellac? I really want to get this project done. I go back to work Wednesday and would feel bad if this was another summer project left undone.
