Long lasting
I bought this for my two cars which are always parked outside in north Florida sun and weather.  Strong water beading lasted for 6 months with washes every 2-3 weeks.  There was still beading after that, but not as strong.  I reapplied instead of waiting to see how long it would go.  I'm ecstatic to wax just twice a year.  Prep included paint cleaner and polish with an orbital.  I wasn't going to clay bar a 10 year old minivan and SUV.
