@T.Albers, I'm sure I've never seen on the forum a more brutal turn in what up to this point had been a very innovative and, for you, satisfying project--after all, what could go wrong with only decal application and a clear coat to conclude the many hours of research and modeling invested in the project.
I'd expect you to remove the ruined paint and refinish what is a superb shell for modeling the UP prototype you've selected.
I look forward to seeing this thread with "Updated (insert date)" in the title soon.
