I should have mentioned that I have the lathe running at slow speed when I apply accelerator. This evenly distributes it around the blank. Accelerator is only a means of speeding up the chemical reactin of the CA. Once it starts, it begins to set the surface of the CA, and any extra accelerator you add is only wasted and runs off of your blank onto the lathe. Keep paper towling on your lathe bed when using CA.

Aerosol sprays should have the same make up as the pump spray, only they are under pressure. They may have different formulas to keep from infringing on patents. Yes, DNA is denatured alcohol, unless you are standing in front of a judge.

I prefer the spray pump because it does not emit a fine mist into the air you are breathing. Wear a mask!! It is also less expensive than the spray cans. You can buy it in 8oz bottles and transfer it to a smaller easier to handle container. Just my choise. Jim S

I use the aerosol stuff, because it produces a finer mist. I run into problems when larger droplets hit the CA. Even with aerosol, I start the spray above the blank and quickly sweep downward until I'm below it before stopping. It's a very quick motion, literally a flick of the wrist.

Thinner coats are always better than thicker. I can get away with using no accelerator with thin CA and blue paper shop towels, but I tend to give it a quick dusting anyway every 4-5 coats to be safe. Others use medium CA sans accelerator, but I don't have great luck with that. Your experience may be different.

If you find something that works for you, by all means share it! I've gotten my method to a pretty reliable level, but I'm always looking for new and better techniques. Billofwrites's airbrush idea sounds promising!

I agree that the pumps deliver too coarse of a mist and that aerosols are finer. If you prefer a fine mist, but want to avoid the higher cost of buying the pressurized aerosol cans, you may want to consider a refillable aerosol can. Yes, these are a bit expensive initially, but considering you can buy the accelerator in 8oz bottles and refill and pressurize the bottle with your air compressor, the cost comes down in a relatively short time.

That's kind of impossible since the aerosol need a carrier and propellent. This is the same reason that medical formularies are chemically different and have different physiological effects than other administration routes.

I like to spray the piece with accelerator and wipe it down with a towel before applying the CA. I get 2 things out of this.. The accelerator helps clean sawdust out of the grain and helps bring the color out a bit more. I can get about 5 coats before the cure time slows down.. let it set up.. spray, wipe and go again..

I've been using Mercury thin CA and love the stuff.

I did the egg that way. Well mostly.. I put 4-5 coats of WTF down before the CA to warm the color up a bit.
