Stubbs, I don't know what you mean by saying your decals have taken a dump? I've been repainting for as long as I've been back in the hobby. I have repainted cars that are now 17 years on the decals and they still look great. Granted, decals can in time fade but I haven't had this problem yet. Maybe you did something in the process of putting them on??
And just as a side note, don't be too confident you will find decals again once made by Microscale. They are dropping a good many 0 scale decals much to my own disappointment. Many are already gone and will not be made again, and that comes from Microscale direct as I talked to them.
I've found a few other companies making decals and at once point recently, posted links for those companies on this forum.
