      Epoxy is a superior product and if the budget allows, is the obvious way to go. My point was that if the budget dictates using the least expensive materials, the old "fiberglass resins" are a lot cheaper than epoxies and they will do an adequate job.

      Epoxy works a lot like polyester but it doesnt' stink, you have a fair
      amount of working time (depending on formula and conditions), it sticks
      better, and the right stuff is low viscosity for wetting out cloth. Of
      course you may need to wait a day or so before it gets strong.

      Sawdust ought to work ok if it really is like talcum powder. The finer
      the better. This is also sold as wood flour. I like to use maybe 80%
      wood flour and 20% silica to thicken epoxy, but I seem to recall wood
      flour alone works ok, just not quite as nicely.

      If you are doing a taped seam over a fillet of thickened epoxy, it will
      go much easier if you can put the tape on while the fillet is still
      really soft or maybe even still wet, so you can squash down all those
      little bumps instead of having to sand (ugh!) or scrape them. This will
      save you a lot of work. Read that epoxy book from System 3. Really.

      Traditional building is really beautiful, but I think in most cases it's
      quite a bit heavier and requires more maintenance. But it sure is pretty.
