It will show any imperfections that are currently there now. You can use a carbon fiber wrap that will somewhat camoflage the area buy it will still be there. The vinyl is very thin... I have some scrap carbon vinyl pm me if youd like a piece to try it out and see what it looks like. No charge of course.
I had a vinyl shop for a while but closed it because everyone wants wraps but nobody wants to pay for one. A good wrap isnt cheap by any means.
