Revell 30ml Decal Soft
About this deal
Now I don't know if finger nail polish remover will work on all decals and it may be too hot for some decals straight out of the bottle, but I'm going to try it on my next decal for the project I'm working on and we'll see what happens IRL. Your local hobby shop will probably sell a decal softener such as Revell’s Decal Soft. That’s what I use and it works fine for me. I use the Microset/Microsol system myself. It's the blue bottle (MICROSET) which should be brushed onto the model. A dilute solution of white vinegar will serve the same purpose of softening the decal film slightly. The red bottle (MICROSOL) is the one that should be applied later and is a stronger solvent. It's one, or several, applications of this which will get that decal snuggled down.

Edit @ October 2016: be very careful when soaking up the excess softener as any agitation can cause the decal to warp or break!
While this is often enough to keep the decal in place, if you feel it necessary you can use the second paint brush to apply the second decal solution on top of the decal. This will set it firmly.

As for acetone, well, better test it on something painted with whatever you used on your model first! For any tight curves or areas that the decal needs to conform to that is not flat, you can apply a little heat using a hairdryer set to low (so as not to distort or melt the decal or model part). Once the decal is in place, carefully warm the area with the hairdryer to make the decal soft so that you can push out any creases or bubbles that may have appeared. We seem to be conflating decal solvent and decal setting solutions in this thread. They are not the same thing.I use Microsol most of the time, but do keep a bottle of Solvaset handy for decals that won't comply.

Decals consist of an image printed onto a thin film. The film is brittle and plastic, in the technical sense that it remembers its shape (a flat sheet) and will try to return to it if possible. That means that unless you’re applying the decal to a perfectly flat surface like a mirror, you’re going to end up with gaps underneath the decal, which will result in bubbles that will ruin the finish. Air gaps beneath the decal will result in an uneven finish
