slightly off-topic, I had my rear window replaced (plastic) the installer cut out the old and sewed in a new one. It was raining the weekend of the install. By the end of the day I noticed droplets inside dripping from the stitching. Naturally, I'm going to call the installer to inform of them of this issue that I didn't have before the $400 install. But how should this be finised? silicone?
