The mixing of epoxy is vary important, and the measuring with some resin's is critical, liquid Oz or by weight. That said I have found for laminating resin's they need to be WELL mixed to get consistent cure. Take Z-poxy is 50/50 by liquid so lets say you want 2 total Oz after mixing, best way I have found is to use graduated medical plastic cups and vary carefully add the parts just to the graduated line's and then stir with out wiping for at least 1minut per Oz, Note this is just my way.
Good Luck
