I used schooner gold on bottom of my board and found it yo be like honey in January- thick and uncompromising.  Somewhere i read do not thin this.  Third coat was an issue with sag etc.  WM didnt have more so i used interlux compass.  I wish i used it first.  Easy self leveling and goes on thin without dilution formulas (10 20 50 percent). Will wrap up board tomorrow and post some photos.  Cheers
