help with sealing and tattoos

Posted in Custom Workstation

I am currently working on a small custom, that has tattoos, since I'm not very good with brushes, and I am a starter in creating customs, I used one of those pens to write on cds, then I sealed it with MSC spray, cause I really like how it makes the plastic look, but it blured the tattoos when it dried, any help on this?
also is this MSC good to seal after I paint with acrylics?
