A lot of people like the Minwax Polycrylic. They claim it's lighter than Epoxy resin, but in all the testing I did a year or so ago I did not find that to be the case, for me anyway. I made several test panels that I weighed as I went, and the Polycrylic panels took more material and more primer to fill weave. It was easier to use, but the finished product with Z-Poxy finishing resin was better and lighter, from a professional painters standpoint. Other peoples results may vary, and everyone has their favorite. Use what works best for you.
