i see all the "official" testing going on, and the obvious results in less than a week and it is clear that this FK stuff just isn't worthy - well - this is worthy enough for me. This car got 215 and 2180 when new, 7 months ago. It sits outside 24.7; it drives up and down the turnpike getting slauhtered with bugs, etc.. It has had 1 additional coat of 2180 about 3 months ago and 1 application of 100fx about 3 weeks ago ( after a particularly nasty weekend trip) Otherwise - it sits outdoors in Florida weather 24/7. Usually gets washed weekly and the hood roof and trunk usually get 425 wipedown after the wash.
