scraping dried silicone off trim is one of my least favorite jobs around the house. That stuff clings like crazy.
Couldn’t agree more—removing old silicone is right up there with cleaning gutters in February. As for those UV-cure adhesives, I’ve tried them on a car mirror once, but window glass is a different beast. They bond well on tiny chips but don’t expect miracles on a big crack, especially if there’s any flex or cold air sneaking in. For bigger cracks, your report cover trick is actually pretty clever—beats dealing with a bigger mess if the glass goes. Just make sure you’re not sealing in moisture, or you’ll get that foggy look between layers.
Yeah, that old silicone is stubborn—sometimes feels like it’s fused to the trim for good. The report cover idea is pretty resourceful in a pinch. Just a heads up, I’ve seen folks accidentally trap moisture under those patches and end up with cloudy glass later. If you can, run a hair dryer over the crack first to be sure it’s bone dry before sealing anything up. Not perfect, but it’ll hold things together until you’re ready for a proper fix.

- Good call on the hair dryer. Moisture under a patch is a recipe for foggy glass or even mold.
- For stubborn silicone, a plastic razor blade works better than metal—less risk of scratching the trim or glass.
- If you’re using a report cover, try to trim it so it only covers the crack, not the whole pane. Less chance of trapping stuff underneath.
- Temporary fixes are fine, but don’t let it ride too long. I’ve seen “just for now” patches stay up for years and turn into a mess to fix later.
- One trick I like: painter’s tape on both sides of the crack before sealing. It keeps the area clean and makes removal easier when you’re ready for the real repair.
