I've almost finished applying CF decals to the floor of RB7. I haven't decided which CF decals to use over exhaust covers. On real car CF pattern is quite hard to see on those covers. So, I'm not so sure if I ever should use CF decals over them. May be I'll leave them just semi-gloss black. Otherwise floor is CFed. I might add some coats of Alclad smoke to tone CF decals down. They look a bit too brown'ish to me. I've used S27's CF 3D decals on the bottom part of the floor. They are too firm to apply over any curved surfaces and non of decal softening solutions I have work on them. But they can be applied over flat surfaces with expensive use of heat from hair drier.
