I think that the acetone would evaporate before you got the top layer in place. It is my experience that if you paint it on the adhesive surface without too much diddling about, the adhesive isn't really soft enough to start smearing before you lay the covering down. You do have to be carefull however that you don't squish all of the adhesive/colour out from under the covering when you press it onto the underylying surface.

Time will tell if my methodology is any good, but I have been getting very nice results by ironing on the covering at a temp that is only as hot as required to melt the adhesive, not hot enough to shrink the material or cause bubbles. Then I go back and wipe some acetone along the edges to lock the trim down.
