It's been almost 3 months now. I've washed the truck 6-7x since then, plus dealt with the uncharacteristic rains we've been having. The cladding still looks pretty much the same as when I applied this stuff, which is surprising. I can see where I applied it unevenly during my initial application, so in a few weeks I plan on re-doing it to see how it turns out. As of right now, I'm very, very pleased.
