I use E_Z Bond cyanoacrylate for pen finishing. One thing with CA is that moisture in the air will cause it to set up. It takes a while but if you don't seal it with the provided cap it will harden after a few weeks to a month. I have some thin CA that is now the consistency of thick CA. Useless. If course it's been on the bench, half full, for about 4 months. You can store unopened bottles in a refrigerator and it will keep for years, in my experience. I also have used Loctite and several other brands with good results.
As for accelerators, they contain acetone, ethyl alcohol, and other ingredients. The reaction between the accelerator and CA is less than a second so don't get the CA on your fingers if you are using accelerator. The reaction can cause nasty burns.
Avoid trying water as it will make a mess and doesn't act as an accelerator.
