I recently discovered that my trailer has been leaking thru the front trim pieces on the corners.This is my fault for not checking more often and keeping up with maintenance.My trailer is metal sided ...

How would one perform maintenance to the corner moldings mentioned by the OP. Given that this type of corner doesn't have caulking, but a thick layer of butyl tape that fills the space between the corrugating of the aluminum siding under and around the molding.
I've wondered this myself, as I have this type of construction. Short of pulling off the moldings and reinstalling them with new butyl tape, what can you do as preventative maintenance?
When I restored my aluminum sided trailer, I attempted to seal all the screws in the roof moldings. I still had a couple of leaks. I then covered the top and sides of the trim with Eternabond tape. That stopped all my trim leaks.
Sealing the screws in the moldings and applying good sealer to any weather exposed edges is the typical process for keeping water out. FWIW, I occasionally perform a pressurized air leak test to the trailer. It uncovers any pinholes or leaks. I use a common furnace squirrel cage blower to push the air inside. Spray bottle of soap and water is the indicating solution. A bubble means a leak.
BTW, installing threaded fasteners through Eternabond tape seals the screw when using a powered driver. The glue rides up the thread and even caps the screw head.
