Hi Jim

 

West system is pretty good but it isn't remarkably better than Jeffco, Saf-T-poxy or any of the other basic resin system's like that.  It fairs well but as pointed out before, it will always have variability in the mix since variaons between batches cant be helped.  Also, acetone can be added to thin it and make it runnier but it does weaken the mix significantly.  And I always use a mix of Cab-O-Sil and balloons since all of one or the other isn't good.  Balloons only makes for a very "dough like" viscosity when it becomes thixotropic.  And all cab-O makes it hard as a rock to sand and is like Vaseline and doesn't spread well.  75% balloons to 25% cab-o works well though.
