Besides the fact that I'm still amazed by your project I'd say the decal problem is according to your skills easy to fix... I would cut out the piece that's stuck on the tape and cut it out of the CF decal sheet again. Add it... done... Though, you'll need clear coat again... Anyways the interior looks amazing and the CF dash is a master piece when it comes to CF skills.
OT, Hiro you seem to have started the MR-2 kit... Is it still in progress or is it on a very very long hold??? I think not only me but loads of other people would be interested in what you'll do with it...
