Thanks guys. Its still slightly there Andy, good camera angle. I tried to get the slight ghost off and it got a bit worse. Let it dry and tried again and it got a bit better. I'm very perplexed as to what is causing the reaction. The surface is gloss coated with Future that set for over 7 days. I'm using a No.1 brush to spread the Mr. Mark setter so its not like its pooling, eating through the Future and causing the reaction. It doesn't react the way with all decals. The one thing I just noticed is that it happens on larger decals, the "NP" above and think back to my PBY build and the reaction occurred on the large wing roundel and the effect happened in the direction I was brushing on the solution. Maybe its reacting with whatever the decal is top-coated with, the bigger the area the worse it gets. Anyhoo.......I've swapped over to Microscale solutions for the remaining few decals
