I left my truck parked in a friends stall at his place while at work one day, when I got back to the truck there was a hardened substance on the seal that runs along the bottom of the driver door window.
It's some form of clear epoxy or glue or cement or something. I was able to scrape it off the lower part of the window though it tore part of that black seal. But there's some that dripped down the door and won't come off! I'm scared to scrape as I don't want to damage paint. I used goo-gone and junk like that. I tried a small bit of paintbrush cleaner, and gasoline without results.
