I have been using thin CA to finish pens for some time without a problem. However recently I found 4 pens where the CA finish is cracking. I have reviewed many posts and see many methods of application but am still confused. I have been using 10 coats of thin CA with activator. As a test I now spray activator on the blank first followed by 4 coats of thin CA without activator. I let the blank dry over night and then micromesh to 12,000 grit. I then apply 3 more coats of thin CA and agin let it dry overnight before again using micromesh. Question: Are others using activator first on the blank before applying CA. Any other thoughts on getting a great finish?
