My project is an expandable Sapele (Mahogany) dining table which I had intended to, and tested, stain, shellac, grain filler, and then wipe on poly. I had some issues with the grain filler but have thinned it and found it eaiser to apply. As some of you have pointed out, the poly is not the best choice if a mirror finish is what I am looking for. I have experimented with Behlens Rock Hard Table Top Varnish but am finding that it has issues with dust and temprature at application and during the cure. Is Sellac and or Laquer that much of a problem when it comes to general durability of a dining table? If you spill a drink will it really destroy Shellac? If a sweating glass sits on a Laquer finish will that to be a problem? It seems like the Rock finish might be the right thing but from what I am seeing, I would have to build a finishing tent that was dust free and heated. One more thing, the finish must be wiped or brushed (no spray gear). Thanks
