Another six weeks have passed, so I thought I'd offer up an update. Sadly the latest version of Tapatalk will not run on my phone, so I don't have a way of easily/quickly uploading any pictures.
Due to some work being done to my house and my garage being turned into a materials storage facility, the car has sat out 24/7 since Feb 1. This also lined up to the time winter finally decided to make an appearance, so the car was subject to nearly four weeks of sub-freezing temps and snow on an almost daily basis. Salt and heavy road grime became the order of the day. For the last two weeks we've seen quite a bit of rain. Needless to say the car has seen the worst of it. Over this time, I've taken it through the touchless car wash once and hand washed it twice.
At this point I'm starting to see the sealant starting to degrade, but not horribly. The water beads are not as tight and uniform like they once were. They are starting to get the big, fat round beads you typically see with many sealants or waxes. Sheeting has slowed noticeably as well. When washing the car the water doesn't slip right off and a flood rinse doesn't leave the car mostly dry like it once did. Again, nothing terrible, but it used to be really good. With the slowing of the sheeting action, the self cleaning has dropped off some too. We're starting to see pollen build up and I've noticed a hard rain won't rinse the car as cleanly as it did last fall.
By my rough calculations, I'll hit the 5-month point next week. Based on what I've seen so far, the sealant should easily make it another month, maybe two. My only question right now is where the lifespan of this product would be if the car didn't live in the garage for nearly two months while I teleworked every day and the weather hadn't been unseasonably mild and dry until February.
