Im trying to wrap my Metra Kit in the Carbon fiber wrap i got off of neffywrap.com, but wrapping the A/C vent holes aren't working very well because of the circle, i tried cutting an X in the middle but it doesnt look very good from the outside, and doesnt hold well either on the inside. anyone else done this have some tips? im using 3m super 77 adhesive it doesnt seem strong enough anybody have a better adhesive?
