This video is great. Super easy to do. Watched this once, took me 2 hours max for the entire job. Used Permatex Glass and Window Sealer. Once I got to taking off the spoiler, I had about 9 Micro-cracks all the way across, I could only see 3 from inside the cab.

Watched this about 20 times before I did it. Mine wasn’t leaking but I had a leak somewhere in the third brake light. Took everything apart one piece at a time. Be patient. For the channel at the top above the glass, I filled it with Flex Seal. Since it’s a rubber, it will flex and less prone of cracking like silicone can. After replacing my light, I also used some black DAP advance exterior window seal on the top outline of the brake light. There was too much of a gap between the spoiler and the light. Also before I put the spoiler back on and the bolts, I used the DAP on all openings and nuts to create a waterproof seal. This video definitely helped!

9-15-23 I did same rear to my 2019 Silverado LTZ. Used the recommended Permatex Sealant. Bought 3 of the Tubes. The Prep. was the hardest of the job. Took headliner down past B pillars. Repair took 2 and 3/4 of the tubes of sealant. Sealant Flows very nicely and seems to be Self Leveling. Followed all the steps here, even covered the small ventilation ports close to the outside frame that was taped off. Very nice job, can't see any of the repair once everything was put back together. Job took 5 Hrs., I was very careful not to scratch Exterior or Interior. Permatex is Grade "A" for this job I cleaned and Waxed all the Painted area under the Spoiler. Spoiler is nice, but design needs improvement. Beer helped tremendously.

When I go to pick it back up I know they gonna try and finesse me into having them fix the window by saying it needs to be replaced. Nah not today you wont!!!!!!

I hate that the brand new smell of it is no more lol

Been in the auto glass business 25 years. We are replacing 2 of these tomorrow under warranty at the dealer. I'm not one to knock anyone's DIY but that permatex is not a good product. Your glass will start leaking again. When it does get an actual tube of auto glass urethane. Go across the entire top with that. We have probably fixed at least fifty of these back glasses. But now the warranty is finally covering them and the back glass has been upgraded where these cracks will not happen anymore.

Is this reseal fix still lasting? There have been many with this issue that report the resealing didn't last for them. Some not at all, some report it lasted for a while. I have seen very few report that the reseal held. I'm just looking for hope that it will last. My 2019 LT has 16 of this fractures/cracks and the dealer resealed it last week. It looks like they did a good job.
