190dcr Posted June 15, 2009 Report Share Posted June 15, 2009 Calhoun Hardener (1)? I had a friend order some for me and need to ask if this stuff is to be mixed into the liquid plastic before you start heating it? thin it into it so to speak? It turns into hard brown lumps when I have tried to use it the last couple time. Color question (#2) If the color does not say non bleeding am I to assume that it will bleed if it touch another color plastic? I'm just a newbie! Thanks in advance! TimD.

jimcline Posted June 16, 2009 Report Share Posted June 16, 2009 Tim, yes you have to mix the hardener and plastic prior to heating. And I mean mix it well. I actually use a hand mixer when I mix mine to make sure it's blended well. Hope this helps, JIM Quote Link to comment Share on other sites More sharing options...
