Yeppers,each facet has to be cut to fit,then trimmed,I did the seams in inconspicuous places and its hard to tell after installed,I dampen a soft cloth with windex for cleaning,last a long time even in the florida sun.I also did the center grill of my car to get a custom look,heres pic's of my 11 year old laying down the strips I had the sign shop cut for me,the dash bezel had to be done by hand.I painted the grille sem trim black first then let steven try his hand at laying down the strip's on the grille.he's seen me lay out flames before and I have let him loose on old sheet metal with spray bomb's and a lil' instruction.
