I don't know how many blanks your pouring at a time but Using small amounts of resin can be more difficult than larger amounts, reducing the room for error in your ratio of equal parts. Usually the top of a pour will be milky because it's harder to mix the resin against the sides and bottom o the cup. Side B is thicker and can often leave swirls of unmixed resin in the cup. I would suggest warming side B with a light bull to around 90-100 degrees (measured with a digital laser thermometer). This will allow it to mix easier and quicker. If your worried about heat and working time, put side A in the refrigerator to cool it down. It won't thicken like side B. Next, take a spade drill bit and break the tip off. Round the sharp edges on a grinder or belt sander and use it in your electric drill to mix the resin. Don't worry about the air bubbles when mixing, the pressure tank will take care of them. Just pour a little extra resin in the mold since it's depth will shrink a little as the bubbles are compressed. Also be sure to keep notes as you work out your issues so you can look back if needed. You'll get it worked out. Good luck and happy casting!
