My experience.
It don't last. I've used the small brown bottle typically found in hobby shops, don't remember the brand but it usually has the shops lable on it and comes with a spray top.
I've found that after a few months the stuff don't work any longer. For whatever reason it seems to slow in it's reaction then quit all together. So I switched.
To Zip Kicker. And it works like a champ. BUT.
It evaporates magically through the bottle. I bought it about a year and a half ago, have used only maybe 3/4 ounce and the bottle is almost empty. Typically I decant the stuff into a needle applicator bottle that gets capped up when not in use. That little bottle only holds about 1/4 ounce and in a month it's empty, even if I only use a few drops.
If you have long set times with your CA it may be time to renew it. The stuff don't last forever and I've found that as it ages it's set time slows, finally to the point of not setting at all, with or without accel.
I like accel and use it most of the time when I'm using CA.
If your CA is fresh and your accel is new that 10 to 15 second wait time you are looking for ain't gonna happen. It's instant, so be sure things are where you want them before applying.
About the sprayer. I don't like them. I like a drop or two right where my work is, not all over evrything in sight. A drop of the accel will creep along your CA so don't worry about uneven application.
