Now I know all of us say fisheyes are caused by surface contaminants. But have any of you had fisheyes develop seemingly without an apparent cause for formation? I'm a fairly sloppy person but I make sure to not touch the epoxy after a fill coat and sometimes those things show up, can pollen in the air cause it? sunspots? I've put fill coats on in a shop with clouds of fine sawdust everywhere and no problems. Could this be one of those Bermuda Triangle issues?
