Actually I did tink about an improper mix so when I did my pot test I mixed in a plsatic medicine cup. I used 3cc each of resin and hardener thinking that the more I use the smaller the error factor. I did use the syringes that came with the 50-50 kit. Under normal circumstances I might think that I've loaded the syringes innaccurately, but my job for 14 years has been injecting dyes for contrast IV testing, so I've loaded somewhere in the neighborhood of 30,000 syringes. Inless we are talking miniscule error factor, I'm confident that my measurements are good. It has been awhile since I bought any flexcoat, and I don't remember for sure but does the hardener have an amber color to it, or is it supposed to be pretty much as clear as the resin. This one's pretty clear. Maybe a test pot with a little more hardener? LOL I might also be just smoking crack and totally screwing up my mix. How many times has overconfidence brought down the wisest men? LOL
