Ya, When I show I use the Endurance on the whole tire, not just the sidewall. It does not look clean and complete unless you do the whole thing. (also Wheel wells) If your not gonna show, i woudn't worry about doing the whole thing!!!!!
The traction does suck thou. It dries but I have still gotten sideways a couple of times leaving a show. Its pretty easy to do. But it does not take long for it to disappear off your tread. I use it on my hard parts as well on my exterior sometime.
LIke MOM said, w/ Zaino you need to use 100% cotton towels...Zaino recommends that you use the ones MADE IN AMERICA!!! evidently the cotton is different and for the best results thats what they recommend!!!!!
Think I"ve got about 78 now, but i'm not for sure...Like i said b4...its THERAPY for me...I really enjoy it! HAVE FUN!!! Topless
