Hi folks...I've learned a lot by reading on this site but this is my first post. I need to replace the gasket on my window glass and I know I can either do so be removing the door and then the window glass or simply leave the door on and remove the glass. This second option seems a bit easier to me. Also once I remove the old gasket what should I use to clean the area before I put on the new gasket? Do I need to apply additional glue to the gasket even though the replacement has adhesive on it. Thanks!
