Heatless Toner Transfer: 

First experiment with this technique: Very successful. 

I used ordinary 70% Isopropyl alcohol with acetone in the ratio given in the YouTube video. 

And, I must admit that my technique was very sloppy. 

With a bit of refinement, I think I would be inclined to use this method over heat transfer 
because it gives very good etch images with an absolute minimum of fuss, bother, and 
unreliable results. 

Next, I will try 70% Iso with Xylene.

Besides: 

You are not going to take a bath in the stuff! 

At most, you will have a few CC's out in the open, or a few eyedroppers' full.
