Long before pen turning we started using the Zap brand products. They had a pump accelerator, but the pump was crappy and failed or came out in globs. When the company went to the aerosol cans it was a vast improvement because you would get consistency throughout the can, not just the first dozen pumps like the old pump bottles did. We began using CA in the restoration of antique furniture. Best thing since sliced bread for chair rungs. But even with the spray if you got too much of it, especially on the thicker CAs you could get the smoking, frosting and cracking. This would ruin a finish job on a chair when it did this and then you would have more work than if you knocked the chair apart and re-glued it. We learned to control the aerosol by aiming well above the target from 18-24 inches away and giving a short burst from the can. This would let a fine mist float down onto the area that we glued. I apply the same technique when using it on pens, for the same reasons. Our hardware store has many people that still do not like the aerosol and will use the pump. We also have people that will not use the pump. Like with anything it is always a personal preference and how you use it. What is most important is what works best for you.
