So it sounds like I definitely want to use TO on top of the decals. Having never used TO before, I had the impression that it would not cure on top on the plastic decal but looks like I was mistaken? If it will cure then it is a no-brainer.

On the topic of DT clear coat vs. TO on the body, if TO will give me similar results with less pain and frustration then I should probably be using it on the body too. In that case, my next question is: will the 90ml bottle be enough for 6+ coats on both neck and body?
