Are you still trying the clear? Try mixing it 1to 1 by volume instead of by weight. I do resin casting. I made the parts that John Teresi has been building. I have been getting better at using the clear resin. I recently discovered that the clear resin I bought from Alumilite and Aeromarine products are the same brand. Alumilite says to mix it by weight and Aeromarine says to mix it by volume. I am a bit confused by this mixed information. I have better luck mixing it by volume. I pour out of smaller containers that are lab grade bottles. Make certain it is mixed very well. Make a good two part mold. Pressure cast it and do not open for at least three days. Making the bubble tops for the Cosma Ray that John built is easy to do now that I have learned not to touch it for awhile. I have a forum that I post a lot of my resin work on. Email me if you still need help.
