One area of a door that is often over-looked because it is not seen, and is prone to rust because of neglect and often because of winter road salts is the bottom of Doors.
Door Jambs can be difficult to deal with, especially at the one end of a door where door hinges and accordion rubber sheathing for wiring resides.
How many I've seen detail their vehicles, and the doors jambs look horrible.
Products such as the WOWA Sealants mentioned sure do make those jobs a lot easier.
I'd commonly use paper towels, or lesser shop towels etc to first remove as much existing and old lubricants on the hinges, door latches and strikes first. Use APC then after if required, and have often employed tools such as soft Paint Brushes, or a long handle detailing brush to massage those lubes and filth out, there are some good ones sold here that work well for the task.
Once satisfied with the cleaning results, carefully flush-rinse, dry.
Then the WOWA Sealants, and again I'd commonly use just cheapo bulk type MF Towels for removal of excess products and finish out. Never no worry of then killing yourself after application trying to dig out and remove any chalky residues in frustration which will occur with virtually all wipe on wipe off sealants and waxes.
Then lastly re-apply lubes to all hinges where required at doors, trunk lids, rear lift glass, hood with a combo of whatever might be required, motor oil commonly with a small squirt can with flexible hose, and greases carefully applied, and excesses removed with either paper towels and/or Kleenex tissue. Job done!
Once doors and such areas are detailed in such a manner and are showroom clean again, it becomes a much easier task for future attention paid to these areas.
