You are doing a fine job just go easy on the 2X it goes a long ways it only takes a drop to mix up 4 ounces of plastic remember the thicker the plastic the darker it will look to you so that's why I take it real easy with the 2X.

I did at one time have about 200 colors from another company and some oddball ones I threw everything in the garbage now we only use 2X thought saying that the others are bad time saying that the 2X will gold twice as far for your money one of the ones that we use a lot chartreuse we order it and big bottles and usually order to add a time because we go through a ton of it in a hurry.
