Yes, the above mentioned by other members is applicable however, the waiting times have a lot to do with the temperature you are working under, in cold and humid places, the drying times are severely affect by it so, as the first precaution, after each CA coat, I would wait a little, a count to 20 will take about 20 seconds, if you don't rush, I will then give it a quick/light spray with the accelerator (I use it in between coats), these 20 seconds is what will determine if you CA surface goes white and bubbly or not, too soon after application is not a good idea, the thicker the CA you use the more prone you are to these troubles, if you don't let if air dry and then use the accelerator to set/cure what was added of CA to the previous coat.
The second suggestion is to double the amount of accelerator 20 seconds after you last application. While you may think that, all the CA layers are dry/set/harden from the wet sanding, micromesh, etc., it is not, even in hot places like Australia, many people prefer to finish it the next day but, I like to finish what I start, in one go so, I replace all those waiting hours with a trick I have used long ago, when restoring antique furniture and all those damn oils that take forever to dry by their own.
In the case with the CA on the pens, I use an electric heat gun on its higher setting, the secret is to work out how far you have to keep the heat gun from the blank, to prevent burning. The temp. you need is 60° celsius so, you turn the heat gun on (high setting) pointed in a safe direction and then, put your free hand in front of the heat gun muzzle, as far as you can reach, you then bring your hand in towards the heat gun until, you feel the heat but, it won't burn but still hot, there is your desired temp.
Now that you know the distance, you point it towards the ROTATING blank(s), moving the heat gun from right to left or viceversa to cover the whole surface of the surface you applied the CA on. You can always play safe and use your free hand to put just behind the turning blank, to make sure, you are not giving too much heat.
The left to right movement should last approx. 1 (one) minute, the lateral movement of the heat gun will prevent spot burning and allow the surface of the CA to heat and cool slightly in between each pass. The speed of those passes should be about 1 second on each way...!
This simple trick will do the same as a overnight drying, in fact, if you work place is very cold and you leave it in that environment all night, if you have really lots of coats of CA on that blanks, 10 ++++, you have a good chance that the CA is not totally cured/harden and if is not, the first thing can happen, is what happened to you, the second is the friction of the sanding on the CA surface can simple bubble up and separate from the wood and the third negative aspect of it is, if the CA is not harden enough, you will be removing more than twice the amount of CA, before you get it smooth and this is what causes the irritating dall spots, that we all like to prevent...!
I'm sorry if my answer to your question is a "bit" longer than most but, I would like to achieve the best results possible so, sharing all these details with you (and other in the same situation) will help you to resolve the situation you found yourself, in...!:wink::biggrin:
