Basically whatever the thinner in the Clear-Lac is, is like paint thinner. I've got both Clear-Lac and Wyoshene (same thing technically). The "obnoxious" smell that they produce is like a Xylene or Toluene(sp?) type thinner. Basically you applied something that is going to "melt" the thin coat of acrylic paint that you put on.
If you can spray the Clear-Lac over your paint job that might work since it wouldn't be rubbing across the paint causing the disolved portion to "travel". I couldn't say though as I pretty much stay away from the acrylics paints because of the terrible job I do with them
