Tamiya Smooth Suface Epoxy Putty

I threw away the box the putty came in, so does anybody know which one is the putty and which one is the hardener? because it says knead together EVEN amounts until light blue color and once I did so my putty dried up really fast before I could form it :banghead: , so I want to add less hardener but dont know which one is the hardener(the white or the blue)

If I misexplained anything just tell me
THANX IN ADVANCE

uhm, if you make them even, they shouldn't dry until 6 hours later. I had to use some putty and cut off like 2mm strips of either one and then kneaded them together. mind you it wasn't light blue, and it dried about 12 hours later. I can still use my fingernail to indent the putty... So if you use even amounts it should work....
