Ready to finish a new dining room table I just built. I want to put a VERY durable finish on it that will NOT allow the wood top to be scratched. I've seen self leveling finishes (at least I think they are self leveling) that are clear and very thick AND allow the grain of the wood to show its beauty. Those I've seen have been used in Marine invironments. I think this would be a good choice to avoid scratches on the table. I originally planned on using a piece of quarter inch plexi or regular glass to protect the table top but have found that method to be cost prohibitive ($600 for the size I need) and I'm not willing to put that kind of $$ out. Does anyone have any experience and / or know of a good product that would fit the bill. Please don't say Polyurethane or Varnish...that would not hold up to the abuse this table will probably take. ANY & ALL advice would be appreciated.
