Well, it worked. I put micro sol on the decals and let it soften them up for about 15 minutes, keeping them wet. Then I dried them off and used Tamiya masking tape to rip them off.
I had to use a toothpick with the end shaved to clean some bits out of the panel lines, but at least it is all gone.
What a relief! Now all I have to do is order another sheet from Eagle Editions.....
