What’s the preferred method of insulating the side and rear doors? I saw Hein’s Utube on insulating passenger front door with Thinsulate (sandwiched Thinsulate between molding and plastic splash protector), but was wondering if insulation is actually being placed inside the cavities of the side and rear doors. If Thinsulate would be used in the door cavities, are there any concerns about potential corrosion? I understand Thinsulate is hydrophobic (doesn’t absorb water), but I’m sure once wetted (water leaking through molding attachment posts, window molding leak, etc.), the Thinsulate would remain damp / wetted through capillary action until it dries out (which could be awhile), and could possibly assist in localized corrosion / rusting inside the door cavity? Any thoughts / guidance on how best to insulate the side and rear doors would be greatly appreciated. Thanks
