It seems like losts of people on here absolutely love using Acetone to smooth over models. Is there any proper way to dilute it down so that it may be used nearly with bare hands? I wouldn't mind if a print sat in it for a couple days.
So you want to submerge the print in a diluted acetone bath?
Just my opinion I don't think it'll turn out well. Stick to the presto part finisher.
Acetone really isn't dangerous in the teaspoon quantities we use it in.

I read that acetone can be diluted with water. There was a post a few weeks ago about a kickstarter campaign that used a water-diluted solvent bath circulated by a pump. If you go ahead and try it, please post your results. I personally think we should encourage new ideas rather than shooting them down.
Acetone is indeed miscible in water:

The trouble is it evaporates much faster, so if you leave an acetone/water mix exposed to atmosphere, most of the acetone it will be gone in a few days. So, you can't really control the concentration well.

I'm not shooting it down blindly. I'm just looking at it like this: We have a way to use a tablespoon of acetone in a $25 device to safely and effectively smooth our prints in a few minutes time. We're proposing a method of managing a diluted solution of acetone and water laying around for much longer, with a considerable amount of more effort, requiring more supervision, and likely costing more than the $25 device to setup. Once a simple solution is found I evaluate everything against that and it needs to improve in either cost, effort, time, safety, or results for it to be worth it for me. This doesn't seem to do any of that.
I am not able to post a link however try this new part finishing idea. Youtube the following NXw5TUTVSb0
Do you have any before and after pics?
I'm guessing the spray has acetone in it.
interesting, I just purchased today a reusable spray can...Takes compressed air input and you can put whatever liquid you have inside. I intend on adding acetone. Tired of this imperfect science of vaporizing acetone.
Looks interesting. I would like to see pics as well.
Sprays hazardous ingredients.
Trichloroethylene (TCE)
Isopropyl Alcohol
Carbon Dioxide
I tried one of those DIY spray cans. With pure acetone, it seemed like the acetone was evaporating from the print before it had a chance to do anything. Maybe the degreaser has some other stuff in it that keeps it on the surface longer.

Did you try freezing the print before hand? I might do the spraying and then keep the part in a can to slow down the escaping.
I was surprised I hadn't heard of anyone trying that before. But it makes sense that you've tried it 
I just sprayed it in the open air, but if you sprayed the print while it was in the bottom of something like a 5 gallon bucket that might help.
Carbon Dioxide
Deadly.

It can be, at least in the morning.
All of this is null and void until we see before and after photos.
I googled an Australian source and found none, hopefully someone in the states can do this soon.
Problem is, from the website he recommeded you need to buy a whole case. Maybe i can call the company and request one can as a sample. But not being an actual mold company i dont know if theyd send one

I'd atleast wear latex/nitrile gloves, and not do it at the kitchen table with the crockpot your planning on using for dinner.. haha
Pregnant women and diabetics naturally produce high levels of acetone... Your body breaks it down quite adequately even at high doses (say like a pregnant diabetic).
Just saying 
I think you should get pregnant and prove it.
Its the delivery that concerns me 
Hey, this is the 21st century, anything is possible these days
No pain; no gain
I've been acetone dipping parts. More for strength than finish, but it does significantly improve the finish.

You are thinking of carbon monoxide. Carbon dioxide is what makes soda fizzy.

I was joking. Actually both are deadly though, admittedly in varying concentrations.
