Thank you for sharing this DIY video. It helped me see someone doing the project. I have a suggestion . Next time, apply only 1 cote of the adhesive to the car body after you scrape or remove the old one. Make sure you clean the area for proper bonding, and you need a primer for the glass. Use same branding on your case 3M; this will be applied to the glass after remov of old glue. And to the car body if there is any metal exposed after scraping. Let it cure and apply adhesives, attach panel, make it even, press gently around all areas, put a bunch of painters tape to prevent glass from sliding down. If you live in cold weather, leave it dry for up to 3 days . If you live in a hot place, one day, it's all you need. Now finally, some windex and you got a new side panel !
Next time go buy a scraper that uses the box blades..it will make your life way easier when scrapping down urathane..also make sure your glue doesn't need activator. Because if you it does and you don't use it. That glue will not hold long.
