I briefly entertained the idea of having stripes put on the Z based on the ones on my 35th LE, but thought better of it. with the checkerflag pattern it was a PITA to detail, esp. claybarring.
my LE has always been garage kept, but the stripes (decals) have held up very well for nearly five years.
I always waxed right over them (Meguiar's NXT), but kept polishes, paint cleaners and claybar away from them.
