I have put other decals over scalemotorsports CF decals before without a problem. But, If you are worried about the CF decal being stuffed, apply a thin clear coat over it before you apply the other decal. If you apply Micro-sol to it, the CF decal underneath might wrinkle slightly again but as long as you dont touch it, it will settle down smoothly again.
BTW, if you're finding that Micro-sol doesn't have enough strength to pull those CF decals down onto curvy surface (Like I did), try some of Pollyscales Polly-Sol Decal softening solution. It's much stronger than Micro-sol and will just about turn the decal into liquid. Just brush it on and let it do its job, and make sure you don't touch the decal while it's wet.
hope this helps.
